What is a a comparison of a machines work output with the works input that is mechanical?
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
How is the efficiency of a machine calculated?
Efficiency = useful output power / input power
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 ?
What is efficiency and how is it calculated?
The efficiency is output divided by input.
How is the efficiency of a compound machine calculated?
The efficiency of a compound machine is calculated by dividing the output work of the machine by the input work. Mathematically, it can be expressed as Efficiency = (Output work / Input work) * 100%. It gives a measure of how well the machine converts input work into useful output work.
In a practical machine the power output is the power input?
In any practical machine, the power output is less than the power input. In other words, the efficiency of real machines is less than 1.smaller thanalways
Is your power into motor equal to your power out of motor at no load?
For a motor's output power to equal its input power, the motor's efficiency must be 100%. As no machine, particularly a rotating machine, can possibly achieve 100% efficiency, there is no condition under which its output power can ever match its input power.
How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
How can a machine's efficiency be calculated?
Machine efficiency can be calculated by dividing the useful output of the machine by its total input, and then multiplying by 100 to express it as a percentage. Useful output could be output energy, work done, or products manufactured, while total input includes energy or fuel consumed. The formula for efficiency is: Efficiency = (Output/Input) x 100%.
How the efficiency of machine be obtained?
Efficiency is output power divided by input power. You somehow have to measure, calculate, or estimate both; the details will vary depending on the type of energy input and energy output.
What factor increases as the efficiency of a machine increases?
The output power of the machine increases as its efficiency improves. This means that more of the input energy is being converted into useful work, leading to higher output power.
What is effIcency of a machine?
Efficiency is the common term for any thing. Usually we give input to perform an act and we derive some output because of that. As far as material machines are concerned definitely output power cannot exceed input power due to conservation of energy. Therefore the ratio of the output power to that of input is defined as efficiency of the machine. Usually it will be given in percentage by muliplying the decimal by 100.
