Power that is used for real work called "Working Power."
Data about a given pump's ability to produce flow against certain head.
Shows the relationship between voltage, current, and resistance in a simple electrical circuit. It applies to both AC and DC circuits.
Device that can be added to a typical AC electric motor that will allow the motor to use different startup method. The purpose of this device is to reduce the strain put on the motor during the typical power-up phase of a motor.
Centrifugal pumps specially designed to move water from an underground well or reservoir.
Refers to the level of water in a well under normal, undisturbed, no pumping conditions.
SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential differences is one volt and the current one ampere.
The amount of the sun's visible light that passes through a window.
Is energy from sources that are naturally replenishing but flow-limited; renewable resources are virtually inexhaustible in duration but limited in the amount of energy that is available per unit of time.
A fast-acting internal breaker that reduces the risk of shock in wet areas.
Power that sets up the magnetic fields in transformers, motors, etc. Also called "Reactive Power."
A diagnostic tool designed to measure the air tightness of buildings and to help locate sources of air leaks.
Is an amount paid by way of reduction, return, or refund on what has already been paid or contributed. It is a type of sales promotion that marketers use primarily as incentives or supplements to product sales.
The ratio of working power, measured in kilowatts (KW) to apparent power, measured in kilovolt amperes (KVA.)
The ratio of cooling output of an air conditioner over a typical cooling season, divided by the energy it uses in watt-hours.
