As power costs rise, it is more vital than ever to know how much power your pump is consuming. This handy guide shows you how.
To calculate the cost of running your pump, we need two figures:
1. The number of kilowatt hours per m³ of liquid, and
2. Cost per kilowatt
Kilowatt Hours Per m³ of Liquid
You can calculate this by using the following formula:
Sg = specific gravity of liquid
Ht = pump total head in meters
367.3 = constant
em = motor efficiency at duty point as a decimal
ep = pump efficiency at duty point as a decimal
Cost per Kilowatt
Check you electricity bill for what your electricity company charges you per kilowatt of electricity used.
