Input temperature of water is 15 °C and outputtemperature is 25 °C. Heat transfer coefficient inside

Input temperature of water is 15 °C and outputtemperature is 25 °C. Heat transfer coefficient inside the tube is 1000 W.m-2.K-1. Calculateoverall heat flow, mass flow of water, heat transfer coefficient on the outer side of the tube,overall heat transfer coefficient and the length of exchanger.Result: Total heat flow is 140 kW, mass flow of water is 3.33 kg.s-1, heat transfercoefficient on the outer tube side is 1055 W.m-2.K-1, overall heat transfer coefficient is35.9 W.m-1.K-1 and the length of exchanger is 6.06 m.VII.3 Vapour of pure ethanol at 78°C is fed into a counter current condenser. All of the vapour iscondensed and then the condensate is subcooled to 20°C. As a cooling media, 0.28 kg.s-1 ofcooling water is used. The water enters at temperature of 10°C and leaves at 65°C. Theoverall heat transfer coefficient for condensation is 1400 W.m-2.K-1
