What is the Formula for calculating the efficiency of a machine?

Anonymous

∙ 14y ago

Updated: 9/18/2023

Efficiency = Output value / Input value

For example, if a machine needs 10 KW to run and produces 8 KW, its power efficiency is 8/10 = 0.8 or 80%

Efficiency is always between 0 and 1 (or 0 and 100 if expressed as a percentage.)
