Design a heat exchanger for a chemical process that requires the transfer of heat from a hot stream containing molten sodium at 1100°C to a cold stream containing water at 25°C. The hot stream inlet flow rate is 1000 kg/hr, and the cold stream outlet temperature should be limited to a maximum of 70°C. The heat transfer coefficient for the tubeside and shellside is 1000 W/m²K and 500 W/m²K, respectively. The design should minimize the size and cost of the heat exchanger while meeting the thermal requirements of the process.
