Example 2.3: Determining the Phase
Based only on the Antoine equation given in Example 2.2, determine the phase of water at
(a) 2 bar, 115 °C, and
(b) 20 bar, 300 °C.
Example 2.5:
Locating the State in the Steam Tables
A 12m3 pressurized vessel contains 200 kg of steam at 40 bar. What is the temperature?
Example 2.11:
Solving Cubic Equations for the Volume
Use the van der Waals, the Soave-Redlich-Kwong, and the Peng-Robinson equations to determine the molar volumes of the saturated phases of ethylene at 260 K (the saturation pressure is 30.35 bar). Compare with the tabulated values,
VL = 0.0713 l/mol, VV = 0.456 l/mol.
