A small steam superheater will be made of 0.75-in. schedule 80 stainless steel pipe which will be exposed to hot flue gas from a boiler. 50 lbm/h of saturated steam at 320F will enter the pipe and be heated to 380F. Assuming that the pipe wall temperature will vary from 375F at the steam inlet to 415F at the outlet, calculate the length of pipe required for the superheater.Ans. 6.1 ft.
