What is the ratio of work put out of a machine to the work put in is its?
It is the efficiency of the machine.
What of the machine compares the output work to the input work and is expressed as a percent?
That's the machine's "efficiency".
Does a refrigerator have 100 percent efficiency?
nothing has 100% efficiency.
What is the ratio of output to input?
efficiency
Can value of the string efficiency being equal to 100 percent?
string efficiency can not be equal to 100%.. cause...1st of all efficiency of anything cannot be equal to 100%.. Secondly when there is insulators and discs to insulate then there will always be a medium between them.. For which there will be voltage drop... Thirdly there will be a conductor to ground voltage drop... So, string efficiency cannot be equal to 100%
How do you calculate the capacity of a machine using formula?

How do you calculate the efficiency of vapour absorption machine?
how to calculate the vapour absorption mechine efficiency and per TR steam consumption
How do you calculate welding machine demand current?
To calculate the current you need to take theWatt rating of your welder and divide this by the voltage youhave setthe machine at- this gives the amperage. So for a 1440 watt welder running at 12v the current would be: 1440 watt/ 12v = 120 Amps
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 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 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 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
