Steam at a rate of 10 g/s exiting the turbine of a power plant at 100 C is to be condensed in a large condenser as shown below. The cooling of steam is achieved by contacting the steam with cooling water at average temperature of 45 C carried in copper pipes with inner diameter 1 cm and outer diameter 1.5 cm. The thermal conductivity of copper is 401 W/mK. The heat of vaporization of water at 100 C is 2257 kJ/kg. The heat transfer coefficients for the copper pipe are 1300 W/m2K and 100 W/m2K on the steam side and cooling water side respectively. What length of copper tube is required?
