ENGINEERING GUIDE

Use the Compressed Air Leak Rate From Receiver Decay Test to calculate leakage from tank pressure decay when compressor is isolated. The calculator uses Receiver/system volume, Start pressure, End pressure, Elapsed time and Air temperature and reports leak flow.

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. 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: Ideal-gas stored-air change / time. The functional engine is shared with related tools in the leak-test family, while this page solves the specific intent represented by receiver decay leak calculator.

Ideal-gas stored-air change / time

Variables and inputs

Receiver/system volume
Start pressure
End pressure
Elapsed time
Air temperature

Worked example

Reproducible example: start with the calculator's default values (Receiver/system volume = 1000; Start pressure = 7; End pressure = 6; Elapsed time = 60) and calculate the result. Then change the variable most relevant to your application and compare the new leak flow against the baseline.

Assumptions and limits

Production must be isolated for load/unload test; receiver/system effective volume and temperature assumptions must be explicit for decay test.

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 rate from receiver decay test on a consistent engineering basis before comparing alternatives.
