094% for sure

Efficiency is the ratio of the energy converted into useful work by the machine to the energy supplied to the machine. Certainly it will not be possible to convert all the energy supplied into useful work because of wastage of energy due to so many reasons. So efficiency will be always less than 1. As the efficiency becomes more the loss would become less. Hence it is desirable.

3760 / 4000 = 0.94 = 94% efficient

Just divide the useful work by the supplied power. If you want to have the answer in percent, multiply the result by 100.

By dividing the useful energy transferred by total energy supplied.

The efficiency ratio for a machine usually refers to the ratio of the useful energy available from a machine and the energy put into it.

If the useful energy output of a system is equal to the energy input, the following calculation can be done:Efficiency = (Useful energy out) / (Energy In)Efficiency = 1Efficiency = 100%Therefore, the machine you describe does have an efficiency value, which is equal to 100%. Very few situations like this exist though, unfortunately.

It depends on the efficiency of the machine. No machine is perfect and there are always losses and waste. Usually the losses are a greater percentage than the useful energy.

High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.

The machine efficiency is 35 percent (35/100).

The idea is to divide the useful work by the input energy.

Such a machine would have an efficiency of 100% and, as the question suggests, it would be a miracle. No real machine is 100% efficient because there are always losses.

An ideal machine is one in which no part of the input energy to the machine gets wasted and the whole input energy is converted into the useful work. The efficiency of such a machine is 100%.

That is called efficiency. An efficiency of 1 (or 100%) means that all the energy is converted into useful work.That is called efficiency.

vague question. Efficiency in terms of energy = useful energy/total energy x 100 vague question. Efficiency in terms of energy = useful energy/total energy x 100

Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The useful output may be electric power, mechanical work, or heat.

useful energy output divided by total energy output x 100 give answer as a percentage, which is why you multiplied by 100

Efficiency = useful output power / input power

efficiency=(useful energy output/ total enerygy)*100

energy efficiency

The efficiency of a machine is found by considering the useful energy or work that comes out of it, and dividing this by the work that you put into it. Multiply by 100 to get the answer in terms of percentage. You should never get more than 100% efficiency, or 100%, since energy will be lost (to heat caused by friction for example).

Is it's Energy Efficiency.

Efficiency

Efficiency for a simple machine is (useful work out) / (total work in). The expression above is usually multiplied by 100 to give percentage efficiency.

efficiencyThe ratio of useful energy to total input energy is called efficiency. It refers to the percentage of the work input that is converted to work output.
