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.
