Radiation from the head is a major source of heat loss from the human body. model a head as a 21-cm-diameter, 20-cm-tall cylinder with a flat top.
if the body's surface temperature is 36? c , what is the net rate of heat loss on a chilly 9? c day? all skin, regardless of color, is effectively black in the infrared where the radiation occurs, so use an emissivity of 0.95.
i have worked it through three times with other written solutions however i cannot arrive at the correct answer. a final answer as well as a solution would be appreciated! !

How can an organ, such as the lungs, work for multiple body systems?
