Hydraulics and industrial maintenance
Hydraulic pressure loss energy cost
Price theoretical dissipated fluid energy across a measured pressure loss, without sizing a line or promising bill savings.
Your inputs
Complete the fields for your selected method. Zero means intentionally zero, not unknown. Currency selection labels amounts; it does not convert exchange rates.
How this calculation works
fluid loss kW=measured pressure drop Pa*flow m3/s/1000; loss kWh=loss kW*hours; energy-equivalent cost=loss kWh*entered price basis.
Δp × flow is fluid power, not measured electrical input. Price is an explicit energy-equivalent basis; result is not attainable electricity savings, safe pressure or line sizing.
What information do I need?
Use records for the same job, equipment or accounting period. Only the fields for your selected entry method are required. An unknown amount is not zero.
Input definitions and where to find them
- Measured pressure drop (psi): Measured differential pressure LOSS across the segment, not maximum operating rating.
- Measured fluid flow (US gal/min): Measured or qualified supplier/assessment value for measured fluid flow at the SAME operating point. Do not infer equipment sizing, safe limits or missing engineering data.
- Period operating time (hours): Use matching records or a clearly identified owner assumption for period operating time, in the displayed unit and the stated row/period scope.
- Entered energy-equivalent price per kWh (selected currency): Explicit FLUID-energy-equivalent price basis; not promised electricity-bill savings.
Use the Where to find this value controls beside the inputs for available work-it-out helpers. Estimates remain your assumptions; a helper does not verify the source figures.
Worked example
Example amounts use US dollars (USD).
Example answer: Theoretical dissipated fluid power is 1.00 kW fluid for the illustrative inputs below.
Example inputs
- Measured pressure drop: 145.037737730217 psi
- Measured fluid flow: 15.850323141489 US gal/min
- Period operating time: 1,000.00 hours
- Entered energy-equivalent price per kWh: $0.15
- Theoretical dissipated fluid power
- 1.00 kW fluid
- Period fluid energy loss
- 1,000.00 kWh fluid
- Energy-equivalent cost
- $150.00
These illustrative values are not recommended rates or industry averages. Replace every example input with your own figures.
Use the result well
Price theoretical dissipated fluid energy across a measured pressure loss, without sizing a line or promising bill savings. Some modes require specialist measurements or a qualified equipment/energy estimate. If you do not have those inputs, use a directly measured alternative where offered; do not guess from unrelated bills or equipment ratings.
Keep inputs on the same scope and time basis. Calculations retain precision internally; displayed values generally round to two decimal places, with extra precision for very small values and whole-unit rounding where required. Economic comparisons describe your supplied assumptions and do not guarantee future results.
