Design a heat exchanger for a chemical plant which produces 1000 kg/hr of a chemical at a temperature of 350°C. The chemical needs to be cooled down to 50°C using water at an inlet temperature of 25°C. The cooling water flow rate should not exceed 5000 kg/hr. The overall heat transfer coefficient should be at least 500 W/m2K. Determine the surface area of the heat exchanger required for this process.
