What is an efficiency ratio?

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.


A machine has an effciency of 91 percent if the energy is supplied to the machine is 4000 watts what is the amount being used for work?

The efficiency of a machine is given by the ratio of useful work output to the energy input. Therefore, if the machine has an efficiency of 91%, the amount being used for work would be 91% of the energy input. In this case, if the energy supplied is 4000 watts, the amount being used for work would be 0.91 * 4000 = 3640 watts.


What is the ratio of the energy delivered by a system to the energy supplied for its operation?

The ratio of the energy delivered by a system to the energy supplied for its operation is known as energy efficiency. It is calculated by dividing the useful energy output by the total energy input and is usually expressed as a percentage. A higher energy efficiency ratio indicates a more efficient system.

The of a machine is the ratio of its energy output to the energy input?

The efficiency of a machine is the ratio of its useful energy output to the total energy input. A higher efficiency value indicates that the machine is converting more of the input energy into useful work output. Efficient machines help minimize energy wastage and improve performance.


Describe why a high-efficiency machine is more desirable than a low-efficiency machine?

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.


What is the efficiency of the machine?

a machine applies a force of 100 newtons over a distance of 10 meters to raise a500 newtons drum 1.5 meters. what is efficiency of the machine ?


Is the efficiency of a machine calculated by the ratio or by the product?

The efficiency of a machine is calculated by the ratio of useful output work to the input work, typically expressed as a percentage. This ratio helps determine how well a machine converts input energy into useful work output.


The efficiency of a real machine?

Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.


The efficiency of a machine is defined as?

The efficiency of a machine is a measure of how well it converts input energy into useful work output. It is calculated as the ratio of useful work output to the total input energy or power. A high efficiency indicates that the machine is able to minimize energy losses and perform its intended function effectively.
