SOLVED: Hot air flows with a mass rate of p = 0.057 kg/s through a smooth uninsulated sheet metal duct of diameter D = 0.15 m which is in the crawlspace of a house. The hot air enters at 0°C and after a distance of t = 5 m cools to 85°C. The heat transfer coefficient between the duct outer surface and the ambient air at T = 0°C is known to be h = 6 W/mK.Calculate the heat loss (W) from the duct over the length L. Determine the heat flux at x = L.
