Wire-to-Water Efficiency Calculator
Overall pumping-plant efficiency from measured flow, head and electrical power.
Field testing needs just a flow meter, two gauges and a power meter. Utilities consider < 55% wire-to-water a rehabilitation trigger.
Formula
Wire-to-Water Efficiency Calculator is a free wire to water efficiency for pump engineers, plumbers and plant designers โ instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Wire-to-Water Efficiency Calculator

Frequently asked questions
What formula does the Wire-to-Water Efficiency Calculator use?+
It computes ฮท_ww = ฯgQH / P_electrical, per ANSI/HI 14.6 โ pump field testing. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Field testing needs just a flow meter, two gauges and a power meter. Utilities consider < 55% wire-to-water a rehabilitation trigger.
Can I use this for pump selection?+
Use it to establish the duty (flow, head, NPSH, power) and then pick a pump whose curve passes through that point near best efficiency. The tool gives you the engineering numbers a supplier will ask for.
Is the Wire-to-Water Efficiency Calculator free to use?+
Yes โ completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
