Humid air at 32 °C , 760 mmHg and 80 % relative humidity is fed to a cooling chamber at constant pressure to condense some of the water vapor out of the humid air. The exit air leaves at 4 °C, 760 mm Hg and 100% relative humidity. If the lquid condensate flows at a rate of 4 kg/h. Calculate the feed rate of humid air in SCMH?
