Calculation of a generic pressure loss in dependence of a pressure loss coefficient.

Generally this function is numerically best used for the incompressible case , where the mass flow rate (m_flow) is known (as state variable) in the used model and the corresponding pressure loss (DP) has to be calculated. On the other hand the function dp_pressureLossCoefficient_MFLOW is numerically best used for the compressible case if the pressure loss (dp) is known (out of pressures as state variable) and the mass flow rate (M_FLOW) has to be calculated. See more information.

DP = dp_pressureLossCoefficient_DP(IN_con, IN_var, m_flow)
