The software calculates the saturated liquid density by using the following equations:
where
Vs,i is the saturated liquid volume for component i
ZRa,i is the Rackett parameter for component i
Tc,i and Pc,i are the critical temperature and pressure for component i, respectively
Tr,i is the reduced temperature for component i
Mixing rule for the Rackett method
We use the linear mixing rule to calculate the saturated liquid volume of the mixture (Vs):
