Calculate the efficiency of a system. Enter the total energy input in to a system, and the total energy or work output to determine it’s efficiency.
Efficiency is the avoidance of waste in any system, often displayed as a percentage of work output to energy input. This energy is usually measure in Joules (J). Efficiency is very often used in applications of heat transfer, since heat loss is a core issue in modern day engineering. It’s also used to evaluate mechanical, solar, and chemical efficiencies.
The formula for efficiency is normal displayed as:
N (efficiency) = Work Output / Energy Input
Where work and energy are measure in Joules.
Multiply the result of the above equation by 100 to get the efficiency as a percentage.
The above explanation is for the use of efficiency in physics and thermodynamics, but efficiency can be used in anything from finance to work performance.
