Steam enters a heat exchanger operating at steady state at 0.1 MPa and 100 degrees C and exits at the same pressure as saturated liquid. The water mass flow rate is 1.5kg/min. A seperate stream of air enters at 30 degrees C and exits at 60 degrees C. Assuming the air behaves as an ideal gas with cp=1.005 KJ/kg*K, determine the mass flow rate of air, in kg/min. Kinetic and potential energy effects are negligble.
