General pressure loss for ideal gas

Calculation of a generic pressure loss for an ideal gas using mean density. See more information.

Generic pressure loss depending on density and viscosity

Calculation of a generic pressure loss in dependence of nominal fluid variables (e.g., nominal density, nominal dynamic viscosity) at an operation point via interpolation. This generic function considers the pressure loss law via a pressure loss exponent and the influence of density and dynamic viscosity on pressure loss. See more information.

Generic pressure loss depending on density

Calculation of a generic pressure loss in dependence of nominal fluid variables (e.g., nominal density) via interpolation from an operation point. See more information.

Generic pressure loss depending on pressure loss coefficient

Calculation of a generic pressure loss in dependence of a pressure loss coefficient. See more information.

Generic pressure loss depending on volume flow rate

Calculation of a generic pressure loss with linear or quadratic dependence on volume flow rate. See more information.
