Radiation Cooling of Body

The basic heat transfer equation for radiation is

where A is the area of the human body and e is the emissivity of the skin. In this case the temperatures must be in kelvins.

Data may be entered for any of the parameters below, and the heat loss rate by radiation will be calculated. Default values will be entered for unspecified parameters, but all values may be changed.

For a skin area A = m^2

and emissivity e = ,

if the temperatures are = °C = K
and = °C = K

then the heat loss rate will be

Q/t = watts.
