Calculate the performance of the heat exchanger specified below for both cocurrent and countercurrent flows.

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.
