Water is present in air at 122 deg F and a total pressure of 14.696 psi in an amount such that the relative humidity is 50%. Water is removed by
1) cooling to 68F at constant pressure
or
2) compressing to 5 atm and subsequent cooling to 68F
In each case calculate:
a) Fraction of original water condensed
b) Molal humidity, humidity and % relative humidity of the resulting gaseous mixture
