Construction of Mollier Diagram

Construct a Mollier diagram for air, when the total pressure of air is 875 mbar. 

2 STATE VALUES OF HUMID AIR MOLLIER DIAGRAMS AND THEIR APPLICATIONS 

First we construct the coordinate system according to the instruc- 

We provide the y-axis x = 0 with temperatures with the help of the equation 

Next we draw the saturation curve in the hj -x coordinate system. Vapor pressures can be calculated with Eqs. (4.106) and (4.108) or taken directly from the tables. The humidity x corresponding to the saturation pressure pi,(t) is calculated with Eq. (4.83) noting that p = 0.875 bar. The enthalpy of humid saturated air is calculated with Eq. (4.94)
