Air at 90.0°C and 1.0 atm (absolute) contains 9.0 mole% water. A continuous stream of this air enters a compressor-condenser, in which the temperature is lowered to 15.6°C and the pressure is raised to 2.90 atm. The air leaving the condenser is then heated isobarically to 100.0°C. Calculate the fraction of water that is condensed from the air, the relative humidity of the outlet air at 100.0°C, and the ratio (m³ outlet air at 100.0°C)/(m³ feed air) at 90.0°C. Fraction of water condensed: Relative humidity of the outlet air: i Volume ratio of outlet to inlet air: i

Transcribed Image Text:Air at 90.0°C and 1.0 atm (absolute) contains 9.0 mole% water. A continuous stream of this air enters a compressor-condenser, in
which the temperature is lowered to 15.6°C and the pressure is raised to 2.90 atm. The air leaving the condenser is then heated
isobarically to 100.0°C. Calculate the fraction of water that is condensed from the air, the relative humidity of the outlet air at
100.0°C, and the ratio (m³ outlet air at 100.0°C)/(m³ feed air) at 90.0°C.
Fraction of water condensed:
i
Relative humidity of the outlet air:
i
Volume ratio of outlet to inlet air:
i
