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?
