Water in turbulent flow is to be heated in a single-pass tubular heat exchanger by steam condensing on the outside of the tubes. The flow rate of the water, its inlet and outlet temperatures, and the steam pressure are fixed. Assuming that the tube wall temperature remains constant, determine the dependence of the total required heat exchanger area on the inside diameter of the tubes.GIVENWater in turbulent flow in tubes with steam condensing on the outsideWater flow rate, inlet and outlet temperatures, and steam pressure are fixedASSUMPTIONSSteady stateFully developed flowTube wall temperature remains constantThe heat exchanger is designed such that the flow is fully developed turbulent flowThermal resistance of the condensing steam is negligibleThermal resistance of the water pipe isnegligible
