Steam exiting the turbine of a steam power plant at 100°F is to be condensed in a large condenser by cooling water flowing through copper pipes (k = 223 Btu/h·ft·°F) of inner diameter 0.4 in and outer diameter 0.6 in at an average temperature of 70°F. The heat of vaporization of water at 100°F is 1037 Btu/lbm. The heat transfer coefficients are 1500 Btu/h·ft2 ·°F on the steam side and 35 Btu/h·ft2 ·°F on the water side. Determine the length of the tube required to condense steam at a rate of 120 lbm/h.
