Compressed Air System Pressure Decay Rate from Leakage calculator computes Pressure Decay Rate in Pa/s using the defined engineering formula and the input values provided. Pressure Decay Rate is expressed in Pa/s. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Leak Conductance = 1.0E-5
  • System Absolute Pressure = 700000
  • System Internal Volume = 2.5
  • System Absolute Temperature = 293.15

Expected Result:

  • Pressure Decay Rate = -2.8

Engineering Interpretation:

Under the given input conditions, the calculated result is: Pressure Decay Rate = -2.8 Pa/s.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
