The human body heat loss is approximately 400 BTUH (117.3 watts).
This is broken down as follows:
RADIATION 150 BTUH (44 WATTS)
CONVECTION 150 BTUH (44 WATTS)
EVAPORATION 100 BTUH (29.3 WATTS)
Air is cooled and falls. Air is warmed and rises. CONVECTION This is the transfer of heat by means of a liquid or a gas, such as air. This is the principle of heat transfer used by such things as electric convection heaters.
EVAPORATION This is the process by which moisture is changed into vapor. As the moisture evaporates from a warm surface, heat is removed and the surface is cooled. An example of ‘ cooling ’ - stepping out of a hot shower.
