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 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.


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 do you need to know to calculate the machinical advantage of a compond machine?

To calculate the mechanical advantage of a compound machine, you need to know the input force applied to the machine, the output force produced by the machine, and the distance over which the input and output forces are exerted. By comparing the input force to the output force, you can determine the mechanical advantage of the compound machine.


What two things you you need to know to calculate mechanical advantage?

To calculate mechanical advantage, you need to know the effort force applied to the machine and the resistance force it is able to overcome. By dividing the resistance force by the effort force, you can determine the mechanical advantage of the machine.

What do you need to know to calculate the mechanical advantage of a compound machine?

To calculate the mechanical advantage of a compound machine, you need to know the input force applied to the machine and the output force obtained from the machine. Additionally, you will need to understand how the individual simple machines within the compound machine are connected or arranged to determine the total mechanical advantage.


What will tell you the efficiency of a chemical reaction?

You need to calculate the yield of the reaction.


How do you measure efficiency on a production line Or to be precise If you know you have downtime for changeovers does this downtime need to be included in the overall efficiency?

To measure if machine is running efficiently you need to calculate the average rate that a machine is operating at, be that kilos per hour, packs per minute etc. To be able to do this accurately you must record all down time, be it down time due to break downs, changeovers, staff rest periods or unavoidable down time that is actually part of your process, just as changing machine parts, wash downs, roll changes etc.

What do you need to know to calculate mechanical advantages?

To calculate mechanical advantage, you need to know the input force and the output force. Mechanical advantage is calculated by dividing the output force by the input force. It provides a measure of how much a machine multiplies force or changes the direction of force.


When you calculate power what do you multiply it by?

If you know the power you do not need to calculate it by anything. And if you don't, the answer will depend on what measure you do know!
