Light passenger vehicles pump up to about 50 litres (13 US gallons) per minute [8] (the United States limits this to 10 US gallons [38 litres] per minute [9]); pumps serving trucks and other large vehicles have a higher flow rate, up to 130 litres (34 US gallons) per minute in the UK [8] and 40 US gallons (150 litres) in the US. This flow rate ...
A water pump. The gallon per watt-hour or (G/Wh) is a formula used to test the efficiency of a pool pump or sump pump. California Title 20
Specific speed N s, is used to characterize turbomachinery speed. [1] Common commercial and industrial practices use dimensioned versions which are of equal utility. Specific speed is most commonly used in pump applications to define the suction specific speed —a quasi non-dimensional number that categorizes pump impellers as to their type and proportions.
In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower, lb/(hp⋅h); in SI units, this corresponds to the inverse of the units of specific energy, kg/J = s 2 /m 2. It may also be thought of as power-specific fuel consumption, for this reason. BSFC allows the fuel efficiency of different engines to ...
Sump pumps tend to require at least 230 volts although smaller models in the United States can sometimes run on 120 volts. Similarly, watt and amp needs of sump pumps can vary. Consumer models can vary from 700 running watts to 2300 watts and more. [1] Gallons per watt-hour is a measure of efficiency in sump pumps.

The SI unit is cubic metres per second (m 3 /s). Another unit used is standard cubic centimetres per minute (SCCM). In US customary units and imperial units, volumetric flow rate is often expressed as cubic feet per second (ft 3 /s) or gallons per minute (either US or imperial definitions).
