Liquid sodium, flowing at 100 kg/s, enters a heat exchanger at 450°C and exits at 350°C. The specific heat of sodium is 1.25 kJ/kg. C. Water enters at 5000 kPa and 20°C. Determine the minimum mass flux of the water so that the water does not completely vaporize. Neglect the pressure drop through the exchanger. Also calculate the rate of heat transfer.
