Design a heat exchanger that can effectively transfer heat between a hot stream of ethanol with a flow rate of 2 kg/s and a cold stream of water with a flow rate of 5 kg/s. The inlet temperature of ethanol is 80°C, while the inlet temperature of water is 20°C. The outlet temperature of ethanol should be 30°C, while the outlet temperature of water should not exceed 35°C. The heat exchanger should have a heat transfer coefficient of at least 500 W/m^2K and a total surface area of no more than 10 m^2.

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.
