Can you please give me an analysis of heat tranfers in heat exchangers?
in a 10-m long center-current flow tubular heat exchanger, a liquid food, flowing in the inner pipe (inside diameter 5 cm), is heated from 4 to 60 C for pasteurization. In the outer tube (diameter 10 cm), hot water enters at 95 C and exits at 80 C. A) If the mass flow rate of the hot water is 5 kg/s, what is the flow rate of the pasteurized product? The specific heat of the water is 4.2 kJ/(kg C), specific heat of product is 3.8 kJ/(kg C) B) what is the log mean temperature difference C) What is the overall heat transfer coefficient for the heat exchanger based on the outside surface?
