Design a heat exchanger for the production of sulfuric acid at a flow rate of 1000 liters per hour. The inlet temperature of the acid is 80°C and the desired outlet temperature is 30°C. The cooling water is available at 20°C and has a flow rate of 2000 liters per hour. Determine the required heat transfer area of the heat exchanger assuming the overall heat transfer coefficient is 800 W/(m²K). What material would you recommend for the heat exchanger tubes and why?
