Determining Shape Factor: Thermal Conductivity and Heat Loss

A thin disk is maintained at 75 degrees celsius and placed on the surface of a large medium maintained at 10 deg C. The thermal conductivity of the medium is 1.4 W/m-deg C, and there is a heat loss of 36 W. The shape factor, S is closest to:

a) 20 cm

b) 40 cm

c) 60 cm

d) 80 cm

Solution Preview

The temperature difference is 75 C (disk temperature) - 10 C Large medium temperature = 65 ...

Solution Summary

This solution calculates the shape factor of a thin disk maintained at a temperature of 75 degrees celsius.
