Section 11 : Expression for Fugacity of a Pure Liquid
Example 6.7
Estimate the fugacity of cyclopentane at 110 C and 275 bar. At 110 C the vapor pressure of cyclopentane is 5.267 bar.
For cyclopentane Tc = 511.8 K, Pc = 45.02 bar, ω = 0.196, Zc = 0.273, Vc = 258 cm/mol, Tn = 322.4 K
T = 383K, P = 275 bar, P3(383K) = 5.267 bar
Tr = 0.7486,
Calculate fsat at the given Vapour pressure by
Virial EOS
Here T = 383K, B is obtained as in problem 18, by B0, B1 .
Final ϕs = 0.9
Now by Rackett equation
