LIQUID VISCOSITY
The following methods are used by CHEMCAD for the calculation of liquid viscosity. The default method
is the DIPPR equation.
Note that the default method for a simulation can be changed. Go to the thermophysical menu and
select transport properties to change the default method. You may also override the basis for the
mixing rule.
1. The DIPPR (Library) Equation
2. The two-term liquid viscosity equation
3. The Letsou Steil method
The ASME method is used for pseudocomponent estimations.
1. The primary method for computing liquid viscosities of a pure component is the DIPPR library
equation which has the following form:
