Efficiency is nothing but calculating how the machine is performing for what it has been made for,
Efficiency is usually calculated in % as (output/input )X100.
for Eg. the Thermal efficiency of an reciprocating gasoline engine can be calculated as follows,
Let,
the input for an reciprocating engine is 12MJ and its out put is 4MJ
then Efficiency is (4/12)X100 = 33%
Work output divided by Work input Times 100
The mechanical efficiency of this machine is 30 percent.
An efficiency factor of 1 (or 100% efficiency) is not possible due to losses that cannot be reduced to zero. These losses take the form of friction, heat loss etc.
Not if the laws of physics - specifically thermodynamics - are correct.
useful energy output divided by total energy output x 100 give answer as a percentage, which is why you multiplied by 100

Efficiency means to calculate that is the machine is efficient enough to save your bill or use less electricity. To calculate the formula is:Efficiency = Energy output (what is the machine producing) divided by Energy input (what is the machine taking or using).
For efficiency, you have to consider the energy or work that you get out of the machine, compared to the energy or work that you put into the machine. Its what you get out, divided by what you put in. By multiplying the result by 100, you should then get the efficiency expressed as a percentage, which is the normal way of describe how efficient a machine or process is. efficiency = (Work out/Work in) x 100 Sometimes you are given the efficiency in a problem, but then have to calculate either the work out or work in, so then its just a case of rearranging the equation above.
The efficiency tells you how good the machine is. Efficiency equals the power output of the machine divided by the power that is input via a shaft, or via electrical wires, or via fuel. So if the machine has a low efficiency it wastes power and energy, which costs money. The average ordinary automobile has an efficiency of 20-25%. A lot of research work goes into improving that figure.
Work output divided by Work input Times 100
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
efficiency formula is (Wout/Win)*100% Wout is the work done by the machine is called the output work Win is the work done by you on a machine is called the input work efficiency= useful work output/work input For science, the effiency is: AMA/IMA * 100
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N
The efficiency of a machine is usually expressed as a percentage. The ideal efficiency of a machine is 100-percent.Another AnswerThere are no units of measurement for efficiency, because you are comparing like with like: output power divided by input power.
Efficiency is output power divided by input power. You somehow have to measure, calculate, or estimate both; the details will vary depending on the type of energy input and energy output.
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
