1. A pipe in a manufacturing plant is transporting superheated vapor at
a mass flow rate of 0.3 kg/s. The pipe is 9 m long, has an inner
diameter of 5 cm and pipe wall thickness of 6 mm. The pipe has a
thermal conductivity of 17 W/m•K and the inner pipe surface
contacted with steam which temperature is 120°C and heat transfer
coefficient h
70 W/m2°C.
If the air temperature in the
