Question

What is the rate of heat conduction (in W) through the 3.50 cm thick fur of a large animal having a 1.70 m2 surface area? Assume that the animal's skin temperature is 33.0°C, that the air temperature is −5.50°C, and that fur has the same thermal conductivity as air. (Assume the thermal conductivity of air is 0.023 J/(s · m · °C).)

Answer 1

Answer: Q=42.45W

Explanation:

Q=πA × ∆t/∆X, where;

Q= Rate of heat

π=coefficient of thermal conductivity

A= Area

∆t= change in temperature

∆x= change in thickness

Q= 0.023 × 1.7 × 33-(-5)/0.035

Q= 0.0391×38/0.035

Q = 1.4858/0.035

Q= 42.45w
