Gear Efficiency = Output Power/Input Power
η = P_out/P_in

What is Efficiency?

Efficiency is the percent of work put into a machine by the user (input work) that becomes work done by the machine (output work). The output work is always less than the input work because some of the input work is used to overcome friction. Therefore, efficiency is always less than 100 percent.

How to Calculate Efficiency of Machine?

Efficiency of Machine calculator uses Gear Efficiency = Output Power/Input Power to calculate the Gear Efficiency, Efficiency of Machine formula is defined as the ratio of output power to input power, providing a measure of how well a machine converts input energy into useful output energy, thereby indicating its performance and effectiveness in converting energy. Gear Efficiency is denoted by η symbol.
