Pump Wire To Water Efficiency
Use this pump wire to water efficiency tool when you have measured values for hydraulic kw, input kw. It applies a transparent mathematical relationship to those values to return an answer in %. Unlike a prediction or recommendation, this is a calculation from your inputs. Motor, pump and drive losses are rolled into one estimate. Enter a different scenario to see how this particular quantity changes; check the assumptions before using it in a project.
How to use this calculator
- Use exact measurements and consistent units for hydraulic kw, input kw.
- Enter each quantity; blank, nonnumeric and out-of-range inputs are not accepted.
- Compare the reported % quantity against your own data and the limitations below.
Formula for Pump Wire To Water Efficiency
% = 100*hydraulic_kw/input_kw. Inputs are expressed in the units shown by the labels.
- This uses a direct fluid relationship and does not retrieve remote data, forecasts or individual account information.
- Motor, pump and drive losses are rolled into one estimate.
Worked examples
Worked example — Pump Wire To Water Efficiency
Enter Hydraulic kw = 5.4, Input kw = 7.8.
Apply 100*hydraulic_kw/input_kw.
Calculated value: approximately 69.23077 %.
Understanding the result
The example produces about 69.23077 %; this is a mathematical output for the example inputs, not an observed result for your project.
Motor, pump and drive losses are rolled into one estimate.
Important notes
Motor, pump and drive losses are rolled into one estimate.
Use values from the same measurement period or physical system. The result is in % and is not a guarantee of capacity, safety, ranking or revenue.
