Description

The component IdealReliefResistor is a model of a flow resistance that behaves as an orifice.

Flow is adjusted via the input signal with nominal flow (as given by Nominal volume flow at Nominal pressure difference) corresponding to an input value of 1 (relative adjustment).

It is parameterized by the parameters Nominal volume flow at Nominal pressure difference, measured with a fluid with Reference density.
