functionreferencePressureLoss
Pressure loss function based on reference values
Extends from Internal.FlowResistance.partialPressureLoss (Partial pressure loss function).
Information
This function calculates the pressure drop according a reference pressure drop at a reference mass flow rate and reference density.
dp/dp_ref = rho_ref/rho * (m_flow/m_flow_ref)^m
The correlation can be assumed to be linear (m=1), quadratic (m=2) or with a custom exponent m.
