Air at 600 K flows with 3 kg/s into a heat exchanger and out at 100°C. How much (kg/s) water coming in at 100 kPa, 20°C can the air heat to the boiling point?

Air at 600 K flows with 3 kg/s into a heat exchanger and out at 100°C. How much (kg/s) water coming in at 100 kPa, 20°C can the air heat to the boiling point? Correct Answer 0.27 kg/s

C.V. :Heat Exchanger, No external heat transfer and no work. Writing the Steady State Energy Equation (SSEE) and putting values, we get the water flow rate at the exit is 0.27 kg/s.
