Suppose the skin temperature of a naked person is 34°C when the person is standing inside a room whose temperature is 26°C. The skin area of the individual is 1.2 m2.

(a) Assuming the emissivity is 0.80, find the net loss of radiant power from the bod

(b) Determine the number of food Calories of energy (1 food Calorie = 4186 J) that is lost in one hour due to the net loss rate obtained in part (a). Metabolic conversion of food into energy replaces this loss.
