Question
The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 68 kg (150 lb) person of height 1.83 m (6.0 ft) would have a body surface area of approximately 1.9 m².
Part A
What is the net amount of heat this person could radiate per second into a room at 19.0° C (about 66.2°F) if his skin's surface temperature is 31.0° C? (At such temperatures, nearly all the heat is infrared radiation, for
which the body's emissivity is 1.0, regardless of the amount of pigment.)
