Efficiency is the quality of being able to do a task successfully, without wasting time or energy. There are many ways to increase agricultural efficiency in the poorer areas of the world. energy efficiency
In a projector efficiency is defined as the ratio of the acoustic power generated to the total electrical power input Efficiency varies with frequency and is expressed as a percentage
{i} competence, productivity (without waste of time or effort); hotel room having a small kitchen area and a table
(gen) The ratio of the ENERGY output to the energy input Efficiency is usually expressed as a percentage F - rendement S - eficiencia
Efficiency is the ratio of the work output to the work input It is normally expressed as a percentage
skillfulness in avoiding wasted time and effort; "she did the work with great efficiency"
is the quantitative ratio of the outputs of a processes to its input, but excluding auxiliary energy or material inputs (these are entered explicitly) Note that the efficiency of energy systems usually refers to the higher heating value, but in other countries also the higher heating value is used (especially USA)
The extent to which a resource, such as electricity, is used for the intended purpose
The ratio of mechanical output to electrical input expressed in percent A measure of the energy losses in a system
Of a device with respect to a physical quantity which may be stored, transferred, or transformed by the device, the ratio of the useful output of the quantity to its total input
The quality of being efficient or producing an effect or effects; efficient power; effectual agency
the ratio of electrical energy delivered into a device to the electrical energy it outputs With respect to audio amplifiers, it is the ratio of the power going into the unit to the power being delivered out to the speakers The higher the number, which is expressed as a percentage, the more efficient the device is, and the lower the amount of energy loss, mostly in the form of heat A perfectly efficient audio device would have a hypothetical efficiency rating of 100%
The ratio of the output to input power times 100, expressed as a percentage Efficiency = (Pout/Pin) x 100
The ratio or percentage of useful output to the total input in any system See Efficient, Energy efficiency, Inefficient
The ratio of output per unit input; the effectiveness of performance of a system; in an ion exchange system, often expressed as the amount of regenerant required to produce a unit of capacity, such as the pounds of salt per kilograin of hardness removal
