Ashell and tube heat exchanger with two shell passes and four tube passes is used to condense saturated refrigerant in the shell at 37.8°c. water enters the tube at 23.1°c and leaves at 28.7°c. refrigerant is to be condensed at a rate of 0.23 kg/s with an enthalpy of vaporization arefrigerant 120 kj/kg. if the overall heat transfer coefficient is 700 w/m2.°c and the heat capacity of water 4.18 kj/kg. °c, calculate the following: log mean temperature difference (lmtd) [3 marks] correction factor, f [4 marks] 6 the area of heat exchanger
