.ThermofluidStream.Processes.Internal.FlowResistance.linearQuadraticPressureLoss

Information

This pressure loss is linear-quadratic in the massflow with the linear factor k and the quadratic factor k2:

dp := k*m_flow + k2*m_flow*abs(m_flow);

For a pure linear pressure loss choose k2 = 0; for a pure quadratic loss choose k=0.
