Question
Transcribed Image Text:3. 24.0 mol/min of humid air at 50 °C and 765 mmHg absolute pressure contains 10.0 mole %
water. A continuous stream of this air enters a compressor-condenser, in which the
temperature is lowered to 20 °C and the pressure is raised to 1700 mmHg. Two streams leave
the process unit; a stream of liquid water and a stream of saturated vapor.
Data: pw (50 °C)=92.51 mmHg, Pw'(20 °C)=17.535 mmHg
a. Determine the Relative Humidity of the air entering the compressor-condenser, h,1?
b. Calculate the mole fraction of water in the saturated vapor stream leaving the
compressor-condenser, yw2?
c. Calculate the molar flowrate of condensed liquid water, ňz.
