An uninsulated steam pipe is used to transport high‐temperature steam from one building to another. The pipe is of 0.5‐m diameter, has a surface temperature of 150°C, and is exposed to ambient air at −10°C. The air moves in cross flow over the pipe with a velocity of 5 m/s. a. What is the heat loss per unit length of pipe?b. Consider the effect of insulating the pipe with a rigid urethane foam (k = 0.026 W/m . K). Evaluate and plot the heat loss as a function of the thickness of the insulation layer for 0 leq delta leq 50 mm.
