A cross-flow heat exchanger with both fluids unmixed has an overall heat transfer coefficient of 200 W/m
Question:
A cross-flow heat exchanger with both fluids unmixed has an overall heat transfer coefficient of 200 W/m2·K, and a heat transfer surface area of 400 m2. The hot fluid has a heat capacity of 40,000 W/K, while the cold fluid has a heat capacity of 80,000 W/K. If the inlet temperatures of both hot and cold fluids are 80°C and 20°C, respectively, determine
(a) The exit temperature of the hot fluid
(b) The rate of heat transfer in the heat exchanger.
