Air has a relative humidity 55% and enthalpy 105kJ/kg dry air and it is cooled down under a constant pressure of 0.1 MPa to a dew point temperature. Find out the air temperature at the beginning of the process, vapour pressure and Dew Point temperature. How much water condensate from the air after the air would be continued to cooled down by 10C from the dew point temperature? Illustrate the process on the psyhrometric chart
