Steam exits the turbine of a steam power plant at 105°F and is to be condensed in a large condenser by cooling water flowing through copper pipes (k = 223 Btu/h · ft • °F) of inner diameter 0.5 in. and outer diameter 0.7 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 130 Ibm/h. O

Why is so Bernulli's principle so important?
