ENGINEERING GUIDE

Use the Compressed Air Leak Percentage From Load/Unload Test to estimate total system leak percentage from compressor load time. The calculator uses Loaded compressor capacity, Loaded time and Total observation time and reports leak flow and % capacity.

How to interpret the result

Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are leak flow and % capacity. Change one input at a time when comparing scenarios so the effect of each variable remains clear.

Formula and methodology

PneumaForge applies this verified method: During isolated no-production test: Q_leak=Q_loaded_capacity·t_loaded/t_total. The functional engine is shared with related tools in the leak-test family, while this page solves the specific intent represented by compressed air leak percentage calculator.

During isolated no-production test: Q_leak=Q_loaded_capacity·t_loaded/t_total.

Variables and inputs

  • Loaded compressor capacity
  • Loaded time
  • Total observation time

Worked example

Reproducible example: start with the calculator's default values (Loaded compressor capacity = 5000; Loaded time = 20; Total observation time = 100) and calculate the result. Then change the variable most relevant to your application and compare the new leak flow and % capacity against the baseline.

Assumptions and limits

Compressor loaded flow assumed equal to stated capacity; unloaded delivered flow approximated zero.

Engineering tips

  • Use your actual electricity tariff and operating hours instead of a generic market price.
  • Use measured compressor specific power when available; ideal thermodynamic estimates are not package performance data.
  • Treat rule-of-thumb pressure savings as assumptions and keep them editable.
  • Keep the inputs used for compressed air leak percentage from load/unload test on a consistent engineering basis before comparing alternatives.

Frequently asked questions

What does the Compressed Air Leak Percentage From Load/Unload Test calculate?

It is designed to estimate total system leak percentage from compressor load time. The reported outputs are leak flow and % capacity.

What inputs does the Compressed Air Leak Percentage From Load/Unload Test use?

The calculator uses Loaded compressor capacity, Loaded time and Total observation time. Only use values that represent the same operating condition or design case.

What formula or method is used?

The calculation follows: During isolated no-production test: Q_leak=Q_loaded_capacity·t_loaded/t_total. The page also states the assumptions that define where the method is valid.

Which assumptions can affect the result?

Compressor loaded flow assumed equal to stated capacity; unloaded delivered flow approximated zero.

Can I use different units?

Yes. PneumaForge converts supported units through canonical engineering units. For compressed-air reference flows and pressure bases, the reference pressure and temperature must also remain consistent.
