PO.EoS.Flash.SRK Function

Description:

PT Flash calculation using SRK EoS. Returns V (vapor fraction), L (liquid fraction), x (liquid composition), y (vapor composition), or K (K-values) based on output parameter.

Excel Function Syntax:

=PO.EoS.Flash.SRK(T, P, zi, props, output, kij)

Parameters:

Parameter	Description
T	Temperature, [K].
P	Pressure, [Pa].
zi	Feed mole fractions (N×1 range, must sum to 1.0).
props	Component properties (N×4 range: Tc, Pc, omega, Mw).
output	'V' for vapor fraction, 'L' for liquid fraction, 'x' for liquid composition, 'y' for vapor composition, 'K' for K-values.
kij	Binary interaction parameter matrix (N×N). Omit in formula for default zeros.
