Question: A 2 0 - c m long rod ( k = 5 0 W m K ) protrudes from a wall. The wall has a

A 20-cm long rod (k=50WmK) protrudes from a wall. The wall has a base temperature of 200
C, and the rod is circular with a diameter of 5 cm . The rod is exposed to a fluid at 40C with a
heat transfer coefficient of 25Wm2K.
Determine the heat transfer dissipated from the rod (W)
Determine the fin efficiency of the rod (%)
