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.
What must you know in order to calculate a machine's efficiency?
To calculate a machine's efficiency, you need to know the input energy (such as electrical or mechanical energy supplied to the machine) and the output energy (work done by the machine). Efficiency is calculated by dividing the output energy by the input energy 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?
To calculate the efficiency of a power plant when you know its heat rate, you can use the equation Efficiency = 3412 / Heat Rate. This equation is derived from the fact that 3412 is the conversion factor for converting British Thermal Units (BTUs) per kilowatt-hour to kilowatt-hours per BTU. By dividing 3412 by the heat rate (measured in BTUs per kilowatt-hour), you can determine the efficiency of the power plant.
Do you need to know the mass of an object to calculate force?
Yes, you need to know the mass of an object in order to calculate the force acting on it. This is because force is directly proportional to mass according to Newton's second law of motion (F = ma).
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.
How do you calculate 1050 miles in gas price for a trip?
You need to know the fuel efficiency of the vehicle when you are driving (driving styles do make a difference).Use the fuel efficiency to calculate the amount of gas you will need and then use the gas price to calculate the cost of fuel.You need to know the fuel efficiency of the vehicle when you are driving (driving styles do make a difference).Use the fuel efficiency to calculate the amount of gas you will need and then use the gas price to calculate the cost of fuel.You need to know the fuel efficiency of the vehicle when you are driving (driving styles do make a difference).Use the fuel efficiency to calculate the amount of gas you will need and then use the gas price to calculate the cost of fuel.You need to know the fuel efficiency of the vehicle when you are driving (driving styles do make a difference).Use the fuel efficiency to calculate the amount of gas you will need and then use the gas price to calculate the cost of fuel.

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
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................................................................................
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 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.
