Abstract:

Evaporation was determined by use of an infra-red gas analyzer. Metabolic heat production was calculated from the rate of oxygen consumption, measured continuously by a closed circuit apparatus. Radiative transfer was calculated from the average wall and skin temperatures which were measured by specially designed thermocouple assemblies. The change in heat content for the entire experiment was determined from changes in the rectal and mean skin temperatures. This value was substituted in the thermal equation, C delta Ht - M E R, to obtain an average rate of convection. This rate of convection was partitioned over short intervals according to the difference between air and mean skin temperatures. The short interval values of convection were then substituted in the thermal equation to give short interval values for delta H.
