Efficiency of a motor?
ratio of energy output to energy input.
The of a machine is the ratio of its energy output to the energy input?
effeciency. study island
What does energy efficiency?
Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The useful output may be electric power, mechanical work, or heat.
What is brake thermal efficiency?
The ratio of brake power output to power input
The ratio output power to input power in percent is called?
B. Efficiency
A comparsion of energy output with energy input?
The result (ratio) of such a comparison is called the efficiency. Note that total energy output must be equal to energy input (conservation of energy); however, what is relevant for this comparison is the useful energy output.
The ratio of output to input power in percent is called?
effciency
What is the input to output ratio formula?
output/input
What do you mean by the term mechanical efficiency of an engine?
It is the ratio of indicated power to brake power.
What is the ratio of the energy a machine delivers to the energy supplied to it?
efficiencyThe ratio of useful energy to total input energy is called efficiency. It refers to the percentage of the work input that is converted to work output.
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
What determines the output voltage and the current of a transformer?
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
