An average man has a body surface area of 1.8 m2  and a skin temperature of 330C. The convective heat transfer coefficient for a clothed person walking in still air is expressed as  h= 8.6V0.53 where V is the walking velocity in m/s. Assuming the average surface temperature of the clothed person to be 300C, determine the rate of heat lost by convection from an average man walking in still air at 100C at a walking velocity of 1.2 m/s.

Question

An average man has a body surface area of 1.8 m2

 and a skin temperature

of 330C. The convective heat transfer coefficient for a clothed person

walking in still air is expressed as

 h= 8.6V0.53 where V is the walking velocity in m/s. Assuming the average

surface temperature of the clothed person to be 300C, determine the rate

of heat lost by convection from an average man walking in still air at 100C at

a walking velocity of 1.2 m/s.
