Steam at 160 ° C flows in a pipe having an inner radius of 50 mm and an outer radius of 55 mm. The convective heat transfer coefficient between the steam and the inner pipe wall is 2500 W / (m² ° C). The outer surface of the pipe exposed to the ambient air is 20 ° C with a convective heat temperature of 10 W / (m² ° C). Assuming a steady state, the rate of heat transfer per meter of pipe from steam to air. The assumed thermal conductivity of stainless steel is 15 W / (m ° C.). Steps of work according to example 4.16 Singh. A. Find the total heat transfer coefficient = W / m² ° C. b. Pipe heat transfer rate = W / m
