modelNominalQuadratic
quadratic pressure loss with nominal values
Extends from ThermalSeparation.PressureLoss.StructuredPackedColumn.BasicPressureLossPacked (basic pressure loss model for a plate column).
Information
Pressure loss model of the form:
delta_p = K*Vdot^2, where K is constant. K is determined from the nominal volume flow rate and the nominal pressure drop of the column.
Parameters
