The cost of pumping water can be calculated as

C = 0.746 Q h c / (3960 μ_{p}μ_{m}) (1)

where

C = cost per hour (USD, EUR, ...)

Q = volume flow (US gpm)

h = head (ft)

c = cost rate per kWh (USD/kWh, EUR/kWh, ....)

μ_{p}= pump efficiency (0 - 1)

μ_{m}= motor efficiency (0 - 1)

### Example - Pumping Cost

*10 US gpm* is lifted *10 ft*. The electricity cost is *0.1 USD/kWh* and the pump and motor efficiency *90% (0.9)*. The cost per our can be calculated as

*C = 0.746 (10 US gpm) (10 ft) (0.1 USD/kWh) / (3960 0.9 0.9) *

* = 0.002 USD*
