Useful power output equation. The useful power output is where. If energy output and input are expressed in the same units efficiency is a dimensionless numberWhere it is not customary or convenient to represent. It can be expressed in power units most commonly kilowatt pferdestärke metric horsepower or horsepowerIn terms of internal combustion engines the engine power usually describes the rated power which is a power output that the engine can maintain over a long period of time according to a certain testing method for example ISO 1585.

The equation that links work done force and distance. The efficiency of a system in electronics and electrical engineering is defined as useful power output divided by the total electrical power consumed a fractional expression typically denoted by the Greek small letter eta η ήτα. For example a car that is 70 efficient will turn 70 of its energy into movement and 30.

An electric machine makes use of 300 J of energy to do work in 10s. How much power does it use. The efficiency of a machine is often given as a percentage.

Measured in watts its exactly equivalent to the power that lights a bulb or moves a car. The equation used to calculate the power is. For example the electricity used to compress natural gas before it is used as fuel in a combustion turbine.

Input to the electric motor is in the form of electrical energy and the output is mechanical energy. M o t o r E f f i c i e n c y M e c h a n i c a l P o w e r E l. The more efficient a process is the less the amount of wasted energy.

Fat Man Thin Man. Efficiency useful output energy total input energy The equation that links efficiency output energy and input. The work output of a system is also described as its Power.
