Design a heat exchanger for a specific process that involves heating a liquid from 20°C to 60°C. The liquid has a flow rate of 500 L/hr, and it will be heated by steam at a pressure of 3 bar. The heat transfer coefficient for the steam is 3000 W/(m²·K), and the overall heat transfer coefficient for the heat exchanger is 500 W/(m²·K). Determine the surface area required for the heat exchanger and the flow rate of steam required to heat the liquid.

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.
