A tube-and-shell heat exchanger with two shell passes and four tube passes (The overall tea transfer coefficient is 700 W/m2 C)is used to condense Freon 12 (enthalpy of vaporization of 120 Kj/kg) in the shell side at 40 C. Water enters the tubes at at 20C and leaves at 27C. What is the water (heat capacity 4.2 Kj/kg) flow rate in order to condense 0.23 Kg/s of Freon 12? Calculate the area of the heat exchanger. If the water rate is reduced to half, how much Freon can be condensed?
