A 65kg, 1.70m tall person is standing in a room.
A) Estimate his body surface arear in square meters
B) Suppose that heat is generated inside his body at a rate of 125W and that this heat is transferred to the surrounding air by radiation alone. Find the air temperature at which the heat transfer rate by radiation is just balanced by the rate of heat generation. Assume the emissivity of human skin is 1 and skin temperature is 34 degrees Celsius.
