Calculate the performance of the heat exchanger Assignment | Get Homework Help

Calculate the performance of the heat exchanger specified below for both cocurrent and countercurrent flows. The hot fluid flow rate is 3 kg/s, and the fluid is to be cooled from 400 K. The cold stream is cooling water at the rate of 4 kg/s available at 300 K. The overall heat transfer coefficient is 800 W/m2 · K. The heat transfer area is 30 m2. The specific heat for both fluids is taken as that of water, 4180 J/kg · K. Also find what the temperatures of the fluids leaving the system would be if the heat exchanger were infinitely long.
