Question

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 = 4.5 kg/min)

B) Determine the relative humidity of the exiting stream [%].
