A person's body temperature is controlled by (1) convective and radiative heat transfer to the surroundings, (2) sweating, (3) respiration by breathing surrounding air and exhaling it at approximately body temperature, (4) blood circulation near the surface of the skin, and (5) metabolic rate. Metabolic rate determines the rate of conversion of chemical to thermal energy within a person's body. The metabolic rate depends on the person's activity level. A unit commonly used to express the metabolic rate for an average person under sedentary conditions (per unit surface area) is called met; 1 met is equal to 58.2 W/m2. Convert this value to Btu/h·ft2. Also, calculate the amount of energy dissipated by an average adult person sleeping for 8 hours if he or she generates 0.7 mets and has a
body surface area of 19.6 ft2. Express your results in Btu and joules (1 Btu = 1055 joules).
