Calculation method
Calculation method
Extrapolated flow at target pressure (litres/s)
Qtarget=Qtest×[(Pstatic−Ptarget)/(Pstatic−Presidual)]^entered exponent; empirical extrapolation only.
Measured pressure drop (kPa)
Qtarget=Qtest×[(Pstatic−Ptarget)/(Pstatic−Presidual)]^entered exponent; empirical extrapolation only.
Symbols and units
- a
- Measured flow (litres/s)
- b
- Static pressure (kPa)

- Measured residual pressure (kPa)
- d
- Target residual pressure (kPa)
- e
- User-specified pressure-flow exponent
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Qtarget=Qtest×[(Pstatic−Ptarget)/(Pstatic−Presidual)]^entered exponent; empirical extrapolation only. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
