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 else can I help you with?
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 do you need to know to calculate the efficiency of a machine?
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.
How do you calculate the efficiency of a power plant when you know its heat rate?
Efficiency = (860.4*100)/(Heat rate in kCal/kWh) or Efficiency = (860.4*4.18*100)/(Heat rate in kJ/kWh) Ex 1: if heat rate is 2500 kCal/kWh, then efficiency is 34.416% Ex 2: if heat rate is 9000 kJ/kWh, then efficiency is 39.96%
Do you need to know the mass of an object to calculate force?
It depends on what else you know. If you know the mass and can measure the acceleration, you can use that to calculate force, but there are other ways to calculate force.
How do you calculate volume if only mass was given?
You would need to know the density of the object in order to calculate the volume from the mass. The formula to calculate volume from mass and density is: Volume = Mass / Density.

I know how to calculate it but what does Efficiency rating actually mean in basketball?
Efficiency rating: ((PTS + REB + AST + STL + BLK) - ((FGA - FGM) + (FTA - FTM) + TO)) / G
Can you calculate a perimeter of a rectangle but not the length of its sides?
no No. You need to know the length of a rectangle's sides in order to calculate the perimeter.
How many amps is 2 hp at 230V 3 phase?
6,25AnswerWithout knowing the efficiency of the motor, it's impossible to tell. The horsepower rating of a motor describes its output power; you need to know its input power in order to calculate its current.
How do you calculate only turbine efficiency not turbine cycle efficiency?
by calculating the inlet steam enthalpy-outlet steam enthalpy we will know the total kcal consumed for output mw required kcal for 1 kwh=860 now campare this with your turbine kcal for 1kwh now you came to know how much is your turbine efficiency................................................................................
How do you calculate angle bar weight?
In order for your to know the weight must know the thickness of the angle bar.
How is distance and time alike?
You need to know both of them in order to calculate speed.
How to calculate fuel efficiency from co2 emission?
To calculate fuel efficiency from CO2 emissions, you need to know the amount of CO2 emitted per unit of fuel burned. This information can be found in emissions data provided by regulatory agencies or fuel suppliers. Once you have this data, you can calculate fuel efficiency by dividing the amount of CO2 emitted by the fuel by the distance traveled or work done. Keep in mind that this calculation provides an indirect measure of fuel efficiency and assumes that the fuel burned was solely responsible for the CO2 emissions.
How do you calculate the efficiency of a power plant when you know its heat rate?
Efficiency = (860.4*100)/(Heat rate in kCal/kWh) or Efficiency = (860.4*4.18*100)/(Heat rate in kJ/kWh) Ex 1: if heat rate is 2500 kCal/kWh, then efficiency is 34.416% Ex 2: if heat rate is 9000 kJ/kWh, then efficiency is 39.96%
