Question

Calculate the rate of heat conduction in watts out of an animal with 3.0cm thick fur. The surface area of the animal is 1.5m^2, its skin temperature is 35C, and the temperature of the surrounding air is 0C. Heat losses due to convection and conduction can be neglected, and the thermal conductivity of the fur can be assumed to be the same as that of air.

Answer 1

P= kA(dT)/L
The thermal conductivity, k, of air is 0.025 W/m*K
A=1.5 m^2
dT = 35 K
L = 0.03m
hence P = 44 W.
