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.
