Description:

KNOWN: A layer of fatty tissue with fixed inside temperature can experience different outside convection conditions.

FIND: a) Ratio of heat loss for different convection conditions

b) Outer surface temperature for different convection conditions

c) Temperature of still air which achieves same cooling as moving air (wind chill effect)

ASSUMPTIONS: 1) Steady-state conditions.

2) One-dimensional conduction through a plane wall.

3) Homogenous medium with constant properties.

4) No internal heat generation (metabolic effects are negligible).

5) Negligible radiation effects.
