E2.1 Compressibility Factor

Example 2.1: Find compressibility factor and specific volume of isopropanol when the following data apply:

T_c = 508.15 °K, P_c = 53 atm,

P = 106 atm, T = 523.15 °K, R = 0.08206 (atm·L)/(mol·°K)

Solution

Reduced pressure, P_r (Equation 2.3):

Reduced temperature, T_r (Equation 2.4):

Compressibility factor, Z (Figure 2.1): Z = 0.33

Specific volume, V (Equation 2.2):
