Design a heat exchanger for a chemical process that involves cooling 1000 kg of a liquid from 80°C to 40°C using water as the cooling fluid. The process flow rate is 5 kg/min and the maximum allowable pressure drop in the heat exchanger is 5 kPa. Assume a heat transfer coefficient of 1000 W/m²K for the liquid and 5000 W/m²K for the water. Design the heat exchanger to occupy a maximum area of 20 m². What is the surface area of the heat exchanger required and what would be the optimal flow configuration?
