What is the percentage of energy used to do work called?
The term EFFICIENCY is defined as useful work, divided by total energy expenditure.
How is the efficiency of a compound machine calculated?
The efficiency of a machine is found by dividing the amount of work done by a machine by the amount of energy used by a machine. The answer is then multiplied by 100 to give a percentage.
What term is used to express the rate at which work is done?
efficiency. Energy output is horsepower
Percentage of energy that is used by a device to perform work is called?
That is called the "efficiency" of the device.
How do you interpret a sankey diagram?
It is a means of saying how much energy is useful and wasted. Has the appliance represented on the diagram got a high or low efficiency; i.e, is there a larger proportion of useful energy compared to that of wasted energy, making the it more efficient. Can you work out the efficiency as a percentage using your knowledge of the equation, Efficieny = useful energy out/ total energy in?

Percentage of energy that is used by a device to work?
efficiency(:
What is the The percentage of energy that is used to preform work?
That is called the "efficiency".
What is a percentage of energy that is used by a device to perform work?
The answer is efficiency.
Percentage of energy that is used by a device to perform work?
Efficiency.
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.
The percentage of energy from a fuel that is actually used to perform work is its?
That is called efficiency. An efficiency of 1 (or 100%) means that all the energy is converted into useful work.That is called efficiency.

Can you get more energy out of fuels if you increase the percentage of energy used for work?
The percentage of energy converted into useful work is called the EFFICIENCY.
How is the efficiency of a compound machine calculated?
The efficiency of a machine is found by dividing the amount of work done by a machine by the amount of energy used by a machine. The answer is then multiplied by 100 to give a percentage.
A machine has an efficiency of 91 percent If the energy supplied to the machine is watts what is the amount being used for work?
If the efficiency is 91%, then work = 0.91 times watts
What is a percentage of energy that is used by a device to perform work called?
The answer to your question is called efficiency
What term is used to express the rate at which work is done?
