Air at T1 = 32°C, p1 = 1 bar, 50% relative humidity enters an insulated chamber operating at steady state with a mass flow rate of 3 kg/min and mixes with a saturated moist air stream entering at T2 = 7°C, p2 = 1 bar. A single mixed stream exits at T3 = 17°C, p3 = 1 bar. Neglect kinetic and potential energy effects
A) Determine mass flow rate of the moist air entering at state 2, in kg/min. (Answer was 4.5 kg/min)
B) Determine the relative humidity of the exiting stream. (Answer was 79.6%)
C) Determine the rate of entropy production, in kJ/min.K.
Need part C. Thank you
