Air at 2 atm and 200 °C, having h= 65 W/m2°C, flows inside a 1 inch steel pipe (outside diameter = 1.315 inch and inside diameter = 0.957 in). The length of the pipe is 1 m. A hot gas with h= 180 W/m2°C flows across the outside of the pipe at 400 °C. Calculate the overall heat-transfer coefficient.
