Design a heat exchanger for a chemical process that requires heating of 50 kg/hr of water from 25°C to 80°C using steam as the heating medium. The available steam is at a pressure of 1.5 MPa and a temperature of 300°C. The overall heat transfer coefficient between the water and the steam is 600 W/m2K. The heat exchanger should be designed to accommodate a temperature drop of 5°C for both the water and the steam. Determine the required surface area of the heat exchanger and the mass flow rate of steam required to meet the process requirements.
