A shell and tube heat exchanger with one shell pass and two tube passes is used to heat 8.82 kg/s of fluid from 15.6 °C to 60 °C by using saturated steam at 150 kPa. The steam is condensing on the outside of the tubes with h= 15 kW/m2.K. There are 50 tubes with an outside diameter of 1.91 cm and a wall thickness of 0.211 cm. If the fouling coefficient on the inside of the tubes is 5678 W/m2.K, determine: A. The length of heat exchanger per one pass B. The pressure drop through the tubes C. The pumping power required when the pump efficiency is 60% E. The wall temperature at each end of the exchanger if the wall thickness of the tube is neglected For turbulent flow, the friction factor is given as: vin = -1.8 log .8 log(+)") The properties of the fluid are given as: p=790 kg/m), K = 0.182 W/m.K, p = 12 x 104 Ns/m2, Cp = 2470 J/kg.K, Pr = 16.29.
