Question
Below a cylindrical pin with a thermal conductivit of 35W/mK is exposed to a fluid at 25C with a heat transfer coefficient of 20W/m^2K. The nodal temperatures are given below and the spacings, dx=2cm, D=2cm.
Determine the heat transfer out the end of the pin.
Explanation / Answer
rate of heat transfer Q = sqrt(hp/ka) (T1 - Tf) tanhml
