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%
What else can I help you with?
How do you calculate the mechanical efficiency of a machine?
Work output divided by Work input Times 100
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
Why is the efficiency of a machine less than 1?
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.
Is a machine physically possible that has an efficiency greater than 100 percent?
Not if the laws of physics - specifically thermodynamics - are correct.
Why is it that efficiency of a machine is less than 1?
The efficiency is always less than one because some of the energy is always useless for what you want. Most wasted energy eventually turns into heat. therefore the efficiency is like a percentage with 1 being 100% a device can't be 100% efficient as some energy is wasted. To work out the efficiency of a device you need to do the total useful energy produced divided by the total energy that is inputted into the device

Explain efficiency and how to calculate it for different simple machines?
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).
What do you need to know to calculate the efficiency of a machine?
To calculate the efficiency of a machine, you need to know the amount of useful work output produced by the machine and the amount of total energy input supplied to the machine. Efficiency is calculated by dividing the useful work output by the total energy input and multiplying by 100 to express it as a percentage.
What must you know in order yo calculate a machine's efficiency?
To calculate a machine's efficiency, you need to know the input energy (total energy put into the machine) and the output energy (useful energy the machine produces). Efficiency is usually calculated as the output energy divided by the input energy, multiplied by 100 to get a percentage.
What information would you use to calculate the efficiency of a machine?
To calculate the efficiency of a machine, you would need information such as the input work or energy applied to the machine and the output work or energy generated by the machine. Efficiency is typically calculated by dividing the output work or energy by the input work or energy and multiplying by 100 to express it as a percentage.
What must you know in order to calculate a machine's efficiency?
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.
How do you calculate efficiency and how is it expressed?
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.
How do you calculate the mechanical efficiency of a machine?
Work output divided by Work input Times 100
Why is a high efficiency machine is more desirable than a low efficiency machine?
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).
Formula to calculate work efficiency?
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
The efficiency of a machine is usually expressed in?
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.
