The process of determining these five words constituted one week of the work done on this thesis. I mean the process of choosing of a suitable subject; one in a field interesting to me, interesting and of value to the engineering world, with a range and depth attainable for me, possible with the available equipment, and approved by the Civil Engineering Department. Research is very interesting for me in any form.because of natural curiosity and a firm confidence in work done by myself. the study of hydraulics in particular, is fascinating; to endeavor to solve by theory, problems involving empirical formulae. That is, I would like to use theorems proven by logic rather than those proven by experiment. Although hydraulics in general has been studied since the time of'the ancient Chinese and their water clock, the practical engineer must use equations based on observation: therefore, every new application or method requires experimentation to govern its use. The subject of this paper is limited enough to be handled with the equipment of the hydraulic laboratory of Michigan State College, and an undergraduate education. . This particular topic was suggested by Professor Leigh, and was approved by Professor Allen, both of the Civil Engineering Department of Michigan State College. I selected this one as the most suitable of the following subjects under consideration: 1. Analysis and guaging of diaphragm valves. 2. Analysis and guaging of multiport valves. 3. Continuation of a previous thesis on flow around model structures in a flume. b. Compilation of the collective data gathered to form the now accepted formulae; a comparison and total analysis. 5. limitations of a partial flume. 6. Redesign of the Michigan State College hydraulic laboratory. 7. River flow into Lake Michigan and beach erosion. This list is included to be of any possible use to future thesis writers. After settling on a topic, the limited facilities of the hydraulic laboratory became apparent, and I looked about for another possible place for the experiment. In the course of this I made a small sur- vey to find the locations on campus with water facilities and a low elevation for a high head for the valves. A list of the eligible places I found is on the next page. However in the end none of these places had enough more head available to make it worthwhile since all the instruments were in the hydraulic lab and would have to be moved back and forth.

I/ A" f . ‘ b- 'v' I [EM/.77 k— Dlapfirmym ‘ " Pressure. ..I EXPLANATION OF A DIAPHRAGM VALVE A diaphragm valve, (see diagram), is motivated by hydraulic pressure on a nonporous diaphragm which is attached circumferentially to the frame of the valve. There is a piston that operates the valve and this is attached to the center of the diaphragm. Movement, therefore, of the diaphragm because of the pressure on it, opens the valve. A spring, opposing themotion of the hydraulic pressure, closes the piston and, therefore, the valve when the pressure is released. VALVES TESTED Herein are the results of head loss calibration trials run on the following valves: a. 2 inch hydraulically operated diaphragm valve made by the Mueller Steam Specialty 00., Long Island, New York. b. 2%"hydraulically operated diaphragm valve made by the holler Steam Specialty Co. c. 16 inch, Model ’40 WR, made by Ross Valve lfg. 00., Troy, LY. d. 16 inch, Model I40 WR "Special", made by Ross Valve Mfg.

Co. f. 8 inch, Model 140 DAWR, Double Acting, 10 inch seat, Ross Mfg. 00. g. 8 inch, Model I40 DAWR, Double Acting, 12 inch seat, Ross Mfg. Co. OPERATING PROCEDURE FOR (2") VALVE The purpose of this project was to find the head loss, or pressure loss, due to the friction.in the valve. This was done at varying velocities or rates of flow of water through the valve. The essential measurements, therefore, were of flow rate and of pressure drop due to the valve. I needed a system that would provide these quantities, and this vac supplied by having a continuous flow and using a stopwatch and scales to determine the weight of water collected in a certain time interval of flow through the valve. I then set up pressure guagss to read the pressure of the water on each side of the valve. The difference therein was the drop due to the friction inside. The City of East Lansing supplied the valve through the courtesy of Mr. Granger; my problem.was to get it installed in the laboratory which is room h of Olds Hall of Engineering. This was a long process for me. It involved picking the most convenient location. collecting the necess- ary connections, and using them in thaproper manner. The location had to be such that it wouldn't interfere with the many classes, (27 hours per week), held in.the room and easily accessable to the maximum.pressure availdble. This location proved to be on an outlet that apparently hadn't been used since Archimedes. After a day of struggle, I managed to have the valve, a master gate valve, two small valves for the pressure readings, a special.%’ pipeline to put pressure on the diaphragm, a pipeline to the weighing apparatus and one to the drain installed. After installing the proper guages, testing the lines, I was ready to roll. The instruments used were sometimes changed so I have them listed with the data. M Op , W F/‘.

I CALIBRATION PROCEDURE FOR (2") VALVE The data for the 2 inch valve was collected and‘with the help of some of the classes in hydraulics enough trials were run to success- fully apply the principle of least squares to get the value for head loss. I used the standard head loss formula: (A sample computation of Trial No. 1 follows each equation.) Head Loss : I x velocity Head H : H x 717?; Then in each trial, knowing the weight per time and the pressure drop from the difference in pressure on each side of the valve, the velocity was found by dividing the weight per unit time by the density of water to get cubic feet per second, ( Q )3 w/r x a = c 300/233 1 62.1. -.- .20299 How the velocity was equal to Q divided by the cross sectional area of the valve pipes Q/a -.- v .20299/.021816 = 9.3117 and the velocity head was the velocity squared, divided.by twice the acceleration of gravity. v.1. Hd. g v92; 1.31463 : 9.31172/ 614.37 The data was collected over the course of two weeks. Some sets of readings had to be thrown out but there was still a wide range of variance in the values. I tried three systems of calculations before settling on the use of logarithams. A sliderule was too inaccurate. a calculating machine carried the result to too many places, and I needed 'the logarithams of the functions to plot. When the values of N were plotted at varying velocities they formed a continuous curve instead of giving a constant value to N. I then plotted the logarithams of head loss versus those of the corresponding velocities to get a new formula. This came out a straight line with a slope of 1.92 and when extrapolated, a y intercept of -.51. The equa- tion of this line therefore is: lg Hd. loss -. 1.92 1 1g Vol. 1, .51. ‘ Taking the anti-log of both sides gives us: Ed. loss :Vel"”‘/3.236 or: Hd. loss =1ve137}2g) x 19.87 This is the true equation and constant for the valve. however, in the standard formula: 3 -_ N x v4/2g N mey'be taken as 15.5 to calculate head loss with an accuracy of plus or minus 1% feet in a range between.h and 15 feet/Second. The forty odd trials in this range have an arithmetical average N of 15.1h8. The use of the true formula gives an accuracy of plus or minus 1 foot at any velocity. ommmc mocswas FOR (2%") um: I encountered a few more problems in setting up the 2%" valve, due mostly to its larger requirements for quantity of flow and larger discharge. The first thing discovered was the complete lack of any 2%" pipe in the lab, necessitating a reducer. Even though Professor Allen would have requisitioned one, this was something the college does not carry, or have to supply its members, I soon discovered. A new one would be too such a strain on my budget and of small value to anyone afterwards. A small search was in order and, bless the happy day, one was to be found in a junk pile in back of the shops which do the repair work for the college. One of he men that works in the plumbing shop there was very kind and out it away from the pipe it had rusted on and rethreaded it. This done, and another session of plumbing and the valve was ready to be tested. I had located this time in a corner of the lab, requiring a longer discharge pipe to reach the drainage facili- ties. This location demanded a tight, leakproof shutoff, for to use the remainderof the lab, water had to be held in the valve. It per- formed admirably in this respect for it was not capped and when the regular classes ran water not a drop leaked out through the valve. Using the same principle of velocity measurement as in the 2" ' valve (finding the discharge weight per unit time) and measuring the inlet pressure and outlet pressure, the difference being the pressure drop, I ran some of the trials using pressure for the diaphragm from the section of pipe immediately preceeding the valve and then some using diaphragm pressure from a remote section. To have a check on these readings, I ran some trials on another identical valve. Also as check runs on this valve I measured velocity by using the theory of a nozzle and just letting the water run out.into atmosphere. This is, of course, merely a rough check. I merely measured the drop of the water coming out of the horizontal valve and arranged a scale to make possible readings of the distance out from the valve that the water reached in this drop. Since there was only one foot of smooth pipe leading out of the valve into atmosphere, I also assumed that the pressure there was negligible and that, therefore, the pressure loss was equal to the pressure going into the valve.

CALIBRATION PROCEDURE FOR (2%") VALVE The application of HzleVZg 01' N .- H/Vz/Eg yeildedthe valves shown on the data sheet for the two identical 2% inch valve, the arithmetical mean of which is 10.33. This was obtained using a steady diaphragm pressure from a remote point. When taking the pressure to operate the valve from the same place, I measured the inlet pressure (is. immediately preceeding the valve in the flow through the valve). The value of N was very different, since a small velocity produced a relatively smaller pressure than a high velocity, the valve wasn't as far open and had a greater constriction and, there- fore, a higher head loss and resulting ”N". These are plotted and form a logarithmic curve with very high values for a small velocity. The trials run as a check by measuring the velocity by nozzle methods gave a consistently lower value for N. The method was only different in regards to method of determining velocity and the assump- tion that the outlet pressure was zero because there was only one foot of pipe leading to atmosphere where pressure must be zero. The velocity was determined by the theory that the water discharg- ing from the valve took a certain time to fall the measured drop due to the acceleration of gravity and the velocity was the distance out it had traveled in this time divided by the said amount of time. Thus since: d :«é g 1‘ Drop =-% 32.17 x (Time)z' or T : (57172? T = m t .559 than v.1. : d/T v.1. z 5.2/.339 : 9.b2 Thexvalues of N'were determined in the standard way of n . Hd. Ion/v72g N . 3/1379 . 2.17 Thesevvalucm increased with an increase of pressure but I think this is duezto the cause that this method of determining velocity reaches a limit around 11.5 feet per second. This is because of the increasing effect of suppression and in spite of increasing velocity the water cannot be projected any farther than a certain limit. The approximate 1: therefore is 2.7 which is only i» of the value determined by the weight per time method. After careful con- sideration Idecided that the error was in the nozzle method since~ it didn't take into consideration any of the factors of turbulence or laminar flow which it depended on to be nonexistent. . For example if we consider the average velocity in the pipe to be é-of that determined by the above method,( which is plausible due to the var- iance in velocity over a cross section of the pipe ), The resulting N 'Ould b6 10e8e CALIBRATION 0F ROSS VALVES I wrote letters of inquiry to eight manufacturers of diaphragm valves but none of them had any information concerning head loss in their valves. I was able, however, from data included in the Ross valve Manufacturing Catalog, which users of their valves had sent to them, to find a few approximate valve values. They gave the gallons per day inlet and outlet pressures pertaining to valves in use. The conversion from gallons per day to cubic feet per second is only a matter of constants and from thence to feet per second by the cross sectional area of the valve. The N resulted from substition into n - a/v‘/2g This gave a value of 16.h5 to the standard and 10.73 to the special Model LO'WR 16 inch valves. Also in the catalog they gave the head loss for their eight inch ho DKWR'with different seat diameters of eight, ten and tweleve inches at varying velocities. With head loss and velocity given, the I was obtained from simple substitution into the standard formula. The values are: I 16 inch, Iodel ho In 16.145 16 inch, Nbdel bO'WR ”Special" 10.73 8 inch, Modellbo DAWR, Double Acting, 8 inch seat 5.21 8 inch, Model 1.0 pm.

REQUIRED PRESSURE 0N DIAPHRAGM By taking each valve out of the system.and merely applying hydraulic pressure to the diaphragm and measuring the action of the valve, I was able to determine the required pressure to open the valve. It required 15#/Eq. inch to open the 2" valve all the way and lO#/3q. inch to open the 2%-inch valve but the total forces thus oppos- ing the spring acre 229f'and 237# due to the respective diaphragm diameters of'h.375 inches and Sé-inches. These valves probably have the same strength spring in each. The motion of the valve‘was-é” for 8# of pressure in the 2% inch valve which would be 380# per inch of motion. C O I HIE l T S the head loss in these valves has a small inverse variation with the size of the valve as the N for the two similar meller valves use less for the 2%” than for the 2" of the same general pattern. The N varied more noticeably with a change in the seat diameter, as we observed in the 8" Ross valves which were of the same size but varied in seat diameter. The larger the seat diameter, the smell the value of N by a greater proportion than that of change in l with change in size of valve. FUNCTIONS OF.A.HYDRAULIC VALVE Hydraulioally operated valves, in general, have certain inherent functions that they are better suited to perform.due to their design; that is, the fact that they are operated and may‘be regulated by fluid pressure. It may be opened and closed by remote control or by the pressure in any part of the system. The former asset is utilized for duties such as procuring more water in a particular district for fire fighting and in directing flow in inaccessible locations. The latter asset is used to maintain any particular maximum or'minimum pressure wherever desired automatically, and in controlling the amount of water in a reservoir or tank, and as pressure reducers. Hydraulic valves also operate quickly whenever speed is desired. These are, of course, only sample uses among the many jobs done. They also require no manual labor. The diaphragm type hydraulic valve, in particular, has been ex- plained is sometimes used as a valve directly and sometimes as a pilot valve to operate larger valves. The inherent advantage of the dia- phragm valve is the relatively larger area of the diaphragm over which the hydraulic is distributed. This supplies a larger force with a smaller pressure and may be designed with a larger area on either the top or the bottom of the diaphragm, thus giving a differential of force for any given pressure. The succeeding pages illustrate some of the various uses of hydraulic valves. STOP CHECK DOUBLE ACTING ALTITUDE VALVES ..

Maintains a constant water level within 3" to 12" variation to prevent tank overflow. 2. Automatically permits, under normal conditions, storage water dis- tribution back through the valve for service consump- tion whenever upstream head drops below static tank head. 3. Instantly closes to conserve storage supply by preventing flow back through valve in case of sudden drop of inlet head below static tank head should the line break. The weighted shot pilot valve is adjustable for any differential pressure for emergency closing of valve under a line-break condition. CONSTRUCTION The valves are furnished special heavy cast iron, semi-steel and cast steel, with full non-corrosive trim of bronze, Gavalloy or stainless steel, depending on the working pressure and water service conditions. Renewable cups and seat washer prevent any metal to metal contacts resulting in minimum servicing costs and repairs. CUSHIONING All water surges and shock are definitely eliminated by the inherent and correct mechanically designed air and water cushioning arrangement as the valve moves into opening and closing positions. The needle valve control permits of governing the speed of valve opera- tion to suit any upstream pressure conditions. With V-shaped port or saw-tooth liner-seat design velocity flow is arrested through the valve as it begins to seat and prevents serious pressure rise or valve banging. ARRANGEMENT While the normal installation position of the valve is vertical in the pipe line, it may be installed in any position and give satisfactory service. Generally the valve is arranged with Base Pilot Type integral with valve lid, but the diaphragm pilot assembly may be separately mounted and piped; or, the diaphragm pilot assembly may be arranged with the Globe Pilot Type in lieu of the Base Pilot Type illustrated.

Valve may be piped in a single supply-discharge line to work ”both ways" as well as arranged with ”stop check" type piston assembly for one way flow service to prevent tank storage return back through valve. CONSTRUCTION The valves are designed with renewable cups and seat washer to prevent metal to metal contacts which results in minimum servicing attention, and economic part replacements. The valve bodies and bonnets are furnished special heavy cast iron, semi-steel and cast steel, with full non-corrosive trim of bronze, Gavalloy or stainless steel, as may be required to suit the work- ing pressures and water service conditions. CUSHIONING In view of surge conditions and water hammer problems existing in most water mains and to eliminate this evil, our valves are particularly designed with inherent correct mechanical air and water cushioning provisions which definitely minimize shock or jar as valve moves into opening or closing positions. With needle valve control it is possible to instantly regulate the speed of valve operation to suit any existing pres- sure condition. Combined with V-shaped port or saw- tooth liner-seat design any velocity flow is arrested through the valve as it begins to close and seat to avoid any disastrous pressure rise or valve closing shock.

This opera- tion assures proper storage water circulation and eliminates any stagnation in the storage supply, and is quite desirable in conjunction with water treatment storage tanks adapting water wheel pumps for chemical mixture. The “Differential" Globe Pilot Control is adjustable to only permit altitude valve opening at any desired minimum tank depth.

The valve is virtually two valves in one, that is, a regular water reducing valve as well as a reverse flow check valve. This valve is ideal for service on pump discharge where a definite service pressure is required to be main- tained and where in case of pump shut-down from any causes the valve will prevent any back flow through the valve to tend to reverse the pump and dissipate storage water back into suction. , srll—IF‘II'—l\ CONSTRUCTION AND DESIGN The valves are furnished special heavy cast iron, semi-steel and cast steel, with bronze trim, Gavalloy or stainless steel, accordingly as to pres- sure and water service conditions. Cushioning by air and water prevents any shock or jar under any varying flow capacities, and the perfectly balanced pilot valve control assures any necessary positioning _of valve to meet volume demands without creating a hunting action in the valve. The “stop check piston” independent of regular valve piston definitely protects against any reverse flow whenever upstream head drops below the , - outlet or downstream pressure. \ OUTLET .‘7 Fig. 49-D, Globe Pilot Pattern ALL DIMENSIONS IN INCHES Size Valve .......................... 3 4 6 8 10 12 14 16 18 20 24 3O 36 Series 15, 25, 30 and 40: Face to Face Flanged Ends .......... l2 13 18 241/9 28%; 31 33 36 4O 4O 48 6O 63 Parts List Page 35 —— Flange Drilling Pages 92 and 93 33 GOLDEN-ANDERSON VALVE SPECIALTY COMPANY WATER PRESSURE REDUCING AND DOUBLE ACTING WATER LEVEL CONTROL VALVES Working Pressures ................. . . _ ................... 150 lbs. 250 lbs. 300 lbs.

Cast Steel 500W OPERATING SEQUENCE This design valve performs three important func- tions. 1. Acting as an altitude control valve to prevent I . any overflow of storage tank and being full open when filling tank. 2. Dissipating tank storage back through the valve at any desired reduced pressure until tank level lowers to a minimum depth. 3. At any minimum depth of water level in tank valve then fully opens to full area to dump remaining tank storage into dis- tribution system. This valve is particularly desired where low and high pressure zones are maintained, and where it is desired to store excess volume under minimum service demands but only dissipate storage from high pressure zone at a reduced pressure until peak load demands when the valve will dump tank storage from high pressure zone at any predetermined minimum tank depth.
