Calculate Properties push button

Figure 11.21 The heart of GUI where the essential steps are carried out upon clicking the Calculate Properties push button. The gas molar volume, liquid molar volume, isothermal compressibility factor (kappa, k) for both phases, thermal expansion coefficient (alpha, a) for both phases, and the compressibility factor (Z) are all estimated for a given selected substance while inputting both the pressure in atmosphere units and temperature in Kelvin. The calculations are based on van der Waals equation of state.
