HEATING VENTILATING AIR CONDITIONING GUIDE 1942 Individual cases may deviate widely, but the tabulation given herewith will serve as a guide to usual heating practice: Air Face Velocity--500 to 800 fpm face, 500 being a common figure.

HEATINC VENTILATING AIR CONDITIONING GUIDE 1942 Had the tank been set 10 ft higher, the head available for friction, while still giving the same pressure at the top fixtures, would have been 0.43 lb X 10 ft or 4.3 lb greater and this, with the 1 lb drop used previously, would give a total allowable drop of 1 lb + 4.3 lb = 5-3 lb which, divided by the 600 ft equivalent run gives a drop per 100 ft of 5.3 X 100 600 0.9 lb.
