Moist air enters an adiabatic humidifier system at 1 atm, 15 °C, with a relative humidity of 20%. The volumetric flow rate of the incoming moist air is 150 m3/min. Saturated water vapor at 1 atm is injected into the flow such that the outlet temperature is 30 °C and the outlet relative humidity is 40%. The pressure is constant in the humidifier system. Determine the mass flow rate of the saturated water vapor entering the humidifier at state 3, in kg/min. Note: The molar mass of air is 28.97 kg/kmol and the value of the universal gas constant is R¯ = 8.314 kJ/(kmol*K)
