Working fluid at 35 F flows in a 2 in pipe. Ambient
temperature is 125 F. The pipe is covered with 2 layers of insulation each
having a thickness of 5 in with k= = 0.015 Btu/ft·h·F and k2 = 0.04
Btu/ft·h·F. The pipe is 0.2 in think with k = 8 Btu/ft h F. Find the rate of
heat transfer to the working fluid in 100 ft of pipe. Assume ha =
200 Btu/ft2 ·h·F and hb = 15 Btu/ft2 ·h·F.
