Water at 20 C flows at 2 m/s over a 2 m length of 35 mm O.D.pipe. Water at 60 C flows inside the pipe at the same speed.Compare h for flow normal to the pipe with that for flow inside thepipe, assuming fully developed flow. If the pipe is copper with awall thickness of 1.4 mm, what is the overall heat transfercoefficient? Which is the largest of the three thermalresistances?
