Hot water is flowing though the center of a AISI 304 stainless steel pipe with a diameter of 300mm, a wall thickness of 10mm and a length of 5m. The pipe is coated with a 2.5mm thick layer of Teflon and covered with a 30mm thick laye of insulation. The water is flowing at a velocity of 0.0015 m/s. Assume the velocity profile to be fully developed. The water is at a temperature of 92°C and the air surrounding the pipe is at 22°C. Some transport properties and dimensions are shown in the table below. 1. What is the heat transfer rate through the pipe and insulation? 2. What is the heat flux at the inner pipe surface and the outer surface of the insulation?
