Question

An aluminum pipe carries steam at 110c. The pipe (kp 185 w/m-k) has an internal diameter of 10 cm and an outside diameter of 12 cm. The pipe is located in a room where the ambient air temperature is 30c and the convective heat transfer coefficient between the pipe and air is 15 w/m2-k. Assume the convective resistance of the steam is negligible. A) determine the heat transfer rate per unit length of pipe
