American Society of Heating and Ventilating Engineers Guide, 1924-25 When buildings are heated from central stations, especially those using steam or vapor, automatic heat control is imperatively necessary, since heat must be available at all times in full power, and it is beyond human ability to manipulate manual controlling apparatus with sufficient nicety to prevent overheating.

American Society of Heating and Ventilating Engineers Guide, 1924-25 reason why mains should be a certain percentage greater area than the sum of the connections, and still lower power consumption can be ob tained by using larger branches and mains of equal area.

American Society of Heating and Ventilating Engineers Guide, 1925-26 Under this condition the capacity of the furnace at the furnace bonnet per square foot of grate area is 43,300 B.t.u. per hour, and per square inch of grate it is 300 B.t.u. per hour.

American Society of Heating and Ventilating Engineers Guide, 1926-27 Length of Run The length of run must not only include the actual linear feet of straight pipe, but also the proper allowance for fittings, valves friction and other items which cause drop in pressure.

American Society of Heating and Ventilating Engineers Guide, 1926-27 quantity of water is the pressure necessary to overcome friction in the pipes (when horizontal) plus the static pressure when the discharge is higher than the supply.
