Aftor déterminin: the total net raciation surface required to survly ths radiaticn loss from tiie rooms, it was necessary to ar-termin> the size cf radiator to install in th> rocms. The computed net area ofthe in stuarc feet cf the radiation surface ,divided by the radiation stbr- face rer stack as civen by the American Fudiator catalozue determines the numver of stacks reyuired for the room. These stacks were then vvilt up into the proper size of radiators for the room under considoration. In the determination of the sive of radiator for the rocm, the height depended on the distance from the floor to the window cill an: was first considered in finding the number of stecks for the room under con-- siceretion . In order that the rediator would not be exce dingly long the width of the stacks ana the number of columns per stack were so proportioned as to be best suited for the room in which they were to be placed. For the ventilation of public buildings each indi- vidual requires a ddfinite amount of Ventilating air per hour. Exprecsed in cubifé feet per hour this value isa constant fortthe case under consideration being about 1800 cubic feet , which is considered cy euthorities as euBficient fo r good ventilation where the occupants 6 of the room are not doing physical exercize.Afeéer dteéer— mining the amount of air necessary for the building the total heat loss by Ventilation is found by arplying hhe formulae:- H' equakts**Q{t-t') /55 H!' *****Heat-loss by Ventilation from the tmilding Q *****Total number of cubic feet of ventilating air required per hour for the building. t ***** Temperature of the air entering the room from the register. +! ***** Temperature of the air in the room. 55 ***** aghe number of degrees through which one cutic foot of air is heated by one &B.T.U. This formulae reduces to :- Hl ee = 3188 Xx Q for t---87,2° +'-~-70,0° The Blenum Fans must deliver the total ventilating air required for the building. Knowing the number of cubic f€8t of air to be delivered to the rooms per hour the number of cubic feet delivered per minute is found. From the American Blower Companies Fah catalogue on Bteel plate type of Fans the capacity of their diff- . erent sizes is given in Cubic feet of air per minute. The back pressure or static pressure agairst which the fan delivers this air is one inch.and size Number 180 ig necessary to completely ventilate the building pro- perlv. The Plenum Coils through which the fan tcekes its Ventilating air to deliver it to the rooms has to be of such a depth with the air passing over the ccils atea specified velocity as to raise the air from outside temperature to the temperature of delivery to the rooms, The limiting velocity of the atr ,acting against a statb pressure in bheemain air duct,ard passing over the coils such that upon leaving the fan it will have attained the proper amount of heat and be most edonomica} in the nume ber of stacks in the heater are given in the Ruffalo Forge Companies Fan an Heater Catalogue. From this data the depth of heater is obtained which will raise the ventilating air from autside to delivery temperature each section of the heater teing four pipes deep. The totel number cf square feet of surface required forthe heater to raise the volume of air to be delivered by the fan to the building tc that degree of temperature necessary to supvly the ventilation loss. The formulae used in the calculation of the heating sure face lis:- Es equale H'/7.8(ts- t pius te ) Re***** Heat surface. H! *#*** Heat Logs by ventilation from the building. 7.8 ***rate of transmission of heat to the air passing through the coils. +****** temperature of air entering the room et the register. ts **** temperature of the steam in the heater. t's *** temperature of the room. This total radiating surface required in the heater divided by the number of coils de-p the heater must be to obtzin the rroper temperature of delivery, gives the num- ber of secuare feet of surface rer stack in the heater, The Buffalo Forge eczstalogue value for the depth of heater reouired to cbtain the proper temperature for the ventil- ating eair,87.2° in thts case checks the velue for the depth of heater eas taken from the J.D.Hoffman Handbook on Heatigggand Ventilating and the requirement ig a depth of trenty pipes or féus sections of “our pipes to a section The size of heater is then obtained by referins to the table on the sizes of Ruffalo Standagtd Heaters. Fer the quantity of air to be delivered by the fan per minute the free air spece is determined by dividing the number of cubic feet supplied by the velocity of the air over the coils in feet per minyte. This value should check the value found for the free air space in the heater dete ermined upon and does within seventy one hundredths of a square foot.vwhich is as close a value as can be obtained. The size of air ducts required for the delivery of the ventilating air to the various rooms is found by :- A------ 144Q/60V A ***** Area of the duct. Q ***** Quantity of air to be supplied by the duct, in cubic feet per hour. V ***** Velocity of the air in the duct at the point et which the secthon is to be determined, Velocity in feet per minute . 144/60 a factor whichm reduces the area of the duct to square-fnches of cross-sectional area, The above formulae applies to any portion of the ventilating @ir duct anc gives a result in square inches from which the dimensions of the duct are determined.

Formulae continued:- RsRadiator surface--Rs- H equals.004 H I.7 --represents the rate at which the radiator surface gives off heat in B.T.U. per square foot per degred difference between the temperature of the air surrounding the radiator and the a average temperature of the heating medium which is taken at 220 for exhaust steam at five pounds gage at which this system receives it .The temperature of the surrounding air being room temperature 70 degrees. In calculating the radiation surface the actual amount as found by the preceeding formulae is increased by twenty five percent to take care of ventilating losses. This formulae reduces to .005 H, With a given quantity of air passing through the main air duct, the calculations for which are shown under the Plenum and Vent- ijlating side of the problem for the size of main duct required and the branch ducts,the velocities of air entering the diff- erent rooms for ventilating purposes was taken depending on the use of the room and the number of occupants between hhe limits of One hundred and Five hundred feet per minute holding close to standard practice, Assuming an air velocity for the register with a known amount of air to be furnished to the room per hour the formulse for the area of the gross register is :- A equals Q!' the ventilating air times 144/60V The fraction 144/60 converts the Quantity of air per hour to the quantity per-minute for the use of V in feet per minute, while the term #@4 makes the final answer in square inches of groes area of register.This formulae takes the form of A equals 3.4 times Q'/V which is applicable for any part of the ventilating ducts in-determining its sectional area. From the gross area of the register the aize of the open- ing is determined , the width of the opening being recorded first and the depth second in my tabulations. The temperature of the steam under five pounds pressure as supplied to the heating system hasa temperature of 220° The temperature of the ventilating air leaving the reg- igtersis 82.9. The temperature of the rooms is to be kept at 70 degrees with an outside temperature of zero degrees thus allowing for the worst possible condition. The preceeding formulae apply to each room individually in determining the several items enumerated. fPhese apply thro- ugh out the building and are used for each room separetely in the galculations. Radiation losses plus twenty five percent of the se losses are supplied by direct radiation , while the Plenum Fan fur- nishes all Ventilation lose in the building.

Ry the constants cof heat transmission the actual rate of passage of the heat Brom the room to the exposed surface in BR.T.U. per square foot per hour per degree of difference of Temperature is allowed for in the total heat loss formulae. The formulae used in determhning the total heat loss from each room by radiation is:-in B.T.U. per hour. Hea&s loss equale-{Glass area (plus) the constant of Heat transmission for that thichness of wall exposed,times the wall area exposedwith the percentageof expossure added (plus) .02 times the number of changes of air required in the room times the total volume of ghe room in cubic feet) all multiplied by thedifference in temperature between the inside and outside air which was taken as seventy degrees for this locallity. All area in this formulae is in square feet and all voluma in cubic feet. For fourth floor losses there has to be added to this formulae,before multiplying by the temperature ,the con- stant for Heat transmission through the cetling times the numbe of square feet of exposed roof area,also I.etimes the total Bquare areacf exposed roofing has to be usedinstead of the actual roof area in order to take eare of the exposure.losses Calculations for the Heat Losses in R.T.U. per hour per degree difference in Temperature, Square inches of net register area for ventilating the rooms, Square feet.. of net radiator suz- face required to supply the radiation loss, The amount of — Ventilating air required for each room in Cubic feet per hour.
