Compressed Air System Efficiency Calculator — Useful Air Power vs Electrical kW
Estimate ideal pneumatic power at point of use from flow and pressure, compare it with measured electrical input and report a transparent system-efficiency indicator.
Inputs
Live results
- Line flow 1.26 m³/min
- Pressure-flow power 14.75 kW
- Screening efficiency 19.7%
- Specific power 7.50 kW/(m³/min)
Formula and method
Ppneumatic≈p·Qactual; η=Ppneumatic/Pelectric.
Worked example
The result makes the large conversion gap between electrical input and useful pressure-flow power visible.
Assumptions and limits
- Uses a simple pressure-volume power screen, not reversible isothermal/exergy efficiency.
- Flow and pressure must be measured at a consistent system boundary.
Frequently asked questions
What does this Compressed Air System Efficiency Calculator calculate?
Estimate ideal pneumatic power at point of use from flow and pressure, compare it with measured electrical input and report a transparent system-efficiency indicator.
Is this suitable for final design?
Use it as a transparent engineering screen. Verify final decisions against measured data, OEM curves, applicable standards and site operating limits.
Why are assumptions visible?
Plant calculations can look precise while hiding uncertain inputs. MAXScanner keeps the governing assumptions visible so scenarios can be checked and compared.
