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. Additionally, sump pumps will typically require an extra burst of power known as additional starting watts to get running. This can be as much as 1.5 times and more than the running watt and amp needs. [2]
1 PSh = 0.73549875 kW⋅h = 2647.7955 kJ (exactly by definition) The horsepower-hour is still used in the railroad industry when sharing motive power (locomotives). For example, if Railroad A borrows a 2,500 horsepower locomotive from Railroad B and operates it for twelve hours, Railroad A owes a debt of (2,500 hp × 12 h) 30,000 hp⋅h.

Watt determined that a horse could turn a mill wheel 144 times in an hour (or 2.4 times a minute). [6] The wheel was 12 feet (3.7 m) in radius; therefore, the horse travelled 2.4 × 2π × 12 feet in one minute. Watt judged that the horse could pull with a force of 180 pounds-force (800 N). [7] So:
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
He was in the submersible for 14 hours on that trip. "I can't even imagine being in there for the number of days they’ve been down there," he said. Hagen said he has no regrets about the ...
For instance, a system which delivers an HSPF of 7.7 will transfer 2.25 times as much heat as electricity consumed over a season. [5] In Europe the term Seasonal Performance Factor ("SPF") is used to mean the same as the average COP over the heating season. A system which transfers 2.25 times as much heat as the electricity consumed is said to ...
