question

Steam at 15.3 KN/m^2 pressure condenses at a rate of 25 kg/hr on a vertical pipe, 56 mm OD. The temperature drop across the film is 5°C. Calculate a) the coefficient of heat transfer, and b) the required length of the pipe

category

engineering

options

  1. Coefficient of heat transfer = 6000 W/m^2-°C, Length of the pipe = 4.2 m
  2. Coefficient of heat transfer = 5000 W/m^2-°C, Length of the pipe = 3.0 m
  3. Coefficient of heat transfer = 4595 W/m^2-°C, Length of the pipe = 2.5 m
  4. Coefficient of heat transfer = 5514 W/m^2-°C, Length of the pipe = 3.4 m
