Design a heat exchanger for a specific process involving the heating of ethanol from 20°C to 80°C. The process flow rate of ethanol is 200 L/hr, and the heating medium is water available at 90°C with a flow rate of 500 L/hr. The heat transfer coefficient for the heat exchanger is 1000 W/m²K. Determine the surface area required for the heat exchanger to achieve the desired heating of ethanol using the given data.
