Air at 80 8 F and a relative humidity of 60% enters the mixing chamber of Fig. 11.34 at a flow rate of 2000 cfm. Another flow of air at 30 8 F and a relative humidity of 30% enters at a flow rate of 1000 cfm. Calculate the temperature, relative humidity, and mass flow rate of the air exiting the mixing chamber. Assume 14.7 psia throughout.
