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.

Design a heat exchanger for a specific process in which a 50,000 kg/day of a mixture with a specific heat capacity of 3.5 kJ/kg.K needs to be heated from 20°C to 70°C using a hot stream of 100,000 kg/day of a fluid with a temperature of 150°C. The heat exchanger needs to operate with a heat transfer coefficient of at least 400 W/m2.K and the pressure drop across the heat exchanger should be no more than 0.5 bar. What type of heat exchanger would be most suitable and what are the dimensions required to achieve the desired performance?
