Hot water at 330 K is transferred through a steel pipe (kpipe = 60 W/m·K) with the outer diameter of 50 mm and the wall thickness of 5 mm. Surrounding environment is air at T¥ = 270 K and V = 10 m/s in cross flow over the pipe. Calculate the heat loss from the pipe to the air per meter of pipe length in W/m.
