American Society of Heating and Ventilating Engineers Guide, 1930 There are three principal factors affecting loss of body heat: (1) tem perature; (2) humidity; (3) air motion.

American Society of Heating and Ventilating Engineers Guide, 1930 The large water content of this type of boiler provides for heat storage capacity against sudden demands and minimizes water line fluctuations under sudden variations in load.
