Calculation reference

What this tool checks.

Leak flow is estimated as compressible flow through a small orifice. Treat results as a prioritization aid, then verify with leak detection or metered data.

Inputs

  • Leak diameter
  • Line pressure
  • Operating hours
  • Energy price
  • Specific power

Outputs

  • Leak flow
  • Annual kWh
  • Annual cost
  • Monthly cost

Engineering guide

Use the result with the right context.

Calculate leak cost calculator from application data and interpret the result for preliminary pneumatic engineering review.

Calculation workflow

  1. Enter the known application values, including Leak diameter, Line pressure, Operating hours.

  2. Run the calculation using one consistent set of units and reference conditions.

  3. Review Leak flow, Annual kWh, Annual cost, then compare the result with the component datasheet and application margin.

Assumptions and limits

  • Keep standard, free-air, and actual compressed-volume reference states consistent throughout the calculation.

  • Confirm compressor, dryer, filter, receiver, pipework, ambient, and operating schedules with measured plant data.

FAQ

Common review questions.

01Tool noteWhy are small compressed-air leaks expensive?

Compressed air is energy intensive to produce. A small leak running many hours per year can consume significant electricity even when it is hard to hear.

02Tool noteHow should I use the cost result?

Use it to prioritize inspection and repair. For audited savings, confirm leak flow with ultrasonic detection, flow meters, or pressure-decay testing.

03Tool noteWhat should I verify after using the Leak Cost Calculator?

Check the entered units and reference conditions, then compare the calculated outputs with manufacturer ratings, application safety margins, transient loads, installation losses, and measured machine performance.
