question

A pipe of 2 in. inner diameter is maintained at a con-stant temperature of 90°F. Water flows through the pipe at an average temperature of 80°F and an average velocity of 7 ft/sec. Assuming fully developed flow and the sur-face of the pipe to be smooth, find the rate of heat transfer to the water over a 15 ft. length of pipe.
