Problem $14$

A mixture of air and water at a temperature of $40C$ and a pressure of $750mmHg$ has a relative humidity of $80\%.$ The wet gas is compressed to $40$ psia and cooled to $20C$ condensing one pound of water per hour in the process.

a$)$ What are the water mole fractions in the inlet and outlet gases?

b$)$ How many cubic feet per minute of original gas were compressed?

c$)$ What is the exit gas flow rate in cubic feet per minute?

Additional Data:

$P_{H2O}^{**}(20C)=17\mathrm{.}535mmHg$ Relative Humidity $=\frac{P_{}}{P_{}}$

$P_{H20}^{**}(40C)=55\mathrm{.}32mmHg$

$P_{H2O}^{**}(60C)=149\mathrm{.}38mmHg$

$P_{H2O}^{**}(80C)=355\mathrm{.}1m$
