How much thermal power does the human body radiate

Reference no: EM13546038

In this problem you will consider the balance of thermalenergy radiated and absorbed by a person. Assume that the person is wearing only a skimpy bathing suit of negligible area. As a rough approximation, the area of a human body may be considered to be that of the sides of a cylinder of length L=2.0 m and circumference C= .8 m. (To simplify things, ignore the circular top and bottom of the cylinder, and just consider the cylindrical sides.) If the emissivity of skin is taken to be e=0.6, and the surface temperature is taken to be T= 30 Celsius , how much thermal power P does the human body radiate?
