A shell-and-tube heat exchanger with 1-shell pass and 20–tube passes is used to heat glycerin in the shell, with hot water in the tubes. The tubes are thin-walled and have a diameter of 4 cm and length of 2 m per pass. The water enters the tubes at 1000C at a rate of 0.5 kg/s and leaves at 550C. The glycerin enters the shell at 150C and leaves at 550C. Determine the mass flow rate of the glycerin and the overall heat transfer coefficient of the heat exchanger.
