A double-pipe heat exchanger operating in the parallel-flow mode carries glycerin in the inner pipe and water in the annular region. The glycerin enters the heat exchanger at 90C at a mass flow rate of 4 kg/s, whereas water enters at 18C at a mass flow rate of 1.5 kg/s. The outside diameter of the inner pipe is 8 cm, the overall heat-transfer coefficient based on the outside surface area of the pipe is 340 W/m2.K, and the heat exchanger is 50 m long. Using the ?-NTU method, find the heat transfer and the outlet temperatures of the glycerin and water
