Question 10.6: A young animal is roughly cylindrical in shape, diameter 20 ...

A young animal is roughly cylindrical in shape, diameter 20 cm. Its core (diameter 16 cm) temperature is 37 °C, skin temperature is 30 °C, and the thermal conductivity of the peripheral tissue is 0.60 W m^{-1} \; k^{-1} . Estimate the heat flux per unit area of the skin surface ignoring heat loss from the ends of the cylindrical shape.

Using Eq. 10.21, G= k'(T_{1} -T_{2} ) /(r_{2} \ln (r_{2} /r_{1} ) ) . Then G = 0.60 × 7/(0.10 ln (0.10/0.08)) = 188 W m^{-2} .
