Suppose the cylindrical segment of Problem 2-122 has a periphery exposed to a convection environment with h

Question:

Suppose the cylindrical segment of Problem 2-122 has a periphery exposed to a convection environment with h = 75 W/m2 · ºC and T∞ = 30ºC instead of to the insulated surface. For this case, one end is at 50ºC while the other end is at 100ºC. What is the heat lost by the segment to the surroundings in this circumstance? What is the heat transfer at each end of the segment?
