A two shell pass and four tube pass heat exchanger is used, Ask an Expert

Engineering

A two shell pass and four tube pass heat exchanger is used to heat glycerine from 20 °C to 55 °C by hot water that enters a thin-walled 22 mm diameter tube at 85 °C and leaves at 42 °C. The total length of the tube in the heat exchanger is 40 m. The convection coefficient on the shell side is 23 W/m2-K and on the water (tube) side is 157 W/m2-K. Calculate the rate of heat transfer (W). Assume the inner and outer diameters are equal for a “thin-walled” tube. In other words, conduction through the tube wall is negligible. ?
