A heat exchanger is to be designed to heat a flow of molten bismuth from 377°C to 477°C. The heat exchanger consists of a 50-mm-ID tube with a surface temperature maintained uniformly at 500°C by an electric heater. Find the length of the tube and the power required to heat 4 kg/s and 8 kg/s of bismuth.
