Efficiency is typically expressed as a percentage, representing the ratio of useful output to input. It can also be expressed as a dimensionless ratio or a specific unit depending on the context, such as miles per gallon for fuel efficiency or lumens per watt for electrical efficiency.

What is the efficiency of a device that gives you 10 units of useful energy for every 100 units you put in it?

The efficiency of the device is 10%. This is calculated by dividing the useful output (10 units) by the input energy (100 units) and multiplying by 100 to get a percentage.


SI unit for efficiency?

Efficiency is normally written as a percentage, and does not have an SI unit."percent". It has no units.


What is the efficiency of a car if you put in 50 units of energy and it gives you 15 units of energy out?

15/50 = 30%


What is the energy efficiency of a light bulb that gives you 30 units of useable energy for every 100 units of energy put into it?

The energy efficiency of the light bulb is 30%. It is calculated by dividing the useable energy output by the energy input, and multiplying by 100 to get the percentage. In this case, 30 units of useable energy divided by 100 units of energy input equals 0.3, or 30%, efficiency.


What is the input of energy for a device that provides 50 units of useful energy and has an efficiency of 0.55?

50 units = (0.55) x (the input)Divide each side of the equation by 0.55 :50 units/0.55 = (the input) = 90.91 units (rounded)


What is the efficiency of a device that gives you 100 units of useful energy for every 100 units you put in it?

The efficiency of the device is 100%. This means that all the energy input into the device is converted into useful energy output without any loss.


How do hetp units contribute to the efficiency of the separation process in chromatography?

HETP units, or Height Equivalent to a Theoretical Plate units, contribute to the efficiency of the separation process in chromatography by measuring the effectiveness of the column in separating compounds. A lower HETP value indicates better separation efficiency, as it means that the column can separate compounds more effectively in a shorter distance. This leads to faster and more accurate separations in chromatography.


The efficiency of a machine is usually expressed in?

The efficiency of a machine is usually expressed as a percentage. The ideal efficiency of a machine is 100-percent.Another AnswerThere are no units of measurement for efficiency, because you are comparing like with like: output power divided by input power.
