Efficiency is usually expressed as a what?
Efficiency is usually expressed as a ratio of output to input, such as output divided by input. It measures the effectiveness of achieving desired results with minimal waste of resources.
Efficiency can be express mathematically as?
Efficiency = Output/Input. This is usually expressed as a percentage but may be given in the form of a ratio.Another AnswerEfficiency is output power divided by input power, normally expressed as a percentage.
What is a quantity usually expressed as a percentage that measures the ration of work output to work input?
Efficiency is a quantity usually expressed as a percentage that measures the ratio of work output to work input. It shows how much of the work input is successfully converted into useful work output.
What ratio of output work to input work expressed as a percent is the of a machine.?
The efficiency of a machine is a measure of the ratio of output work to input work, expressed as a percentage. It is calculated as: Efficiency = (Output Work / Input Work) x 100% A more efficient machine will have a higher percentage, indicating that a greater percentage of input work is being converted to useful output work.
What is the formula of efficiency?
Efficiency is typically calculated as the ratio of actual output to maximum possible output, expressed as a percentage. The formula for efficiency is: Efficiency = (Actual output / Maximum possible output) * 100%.
What is the implication of negative voltage gain?
If the input and output are expressed in volts, then negative gain means a 180° phase shift. If the ratio of output to input is expressed in dB, then negative gain means attenuation, i.e., less power out than power in.
What is the unit of efficiency?
Efficiency is typically expressed as a percentage, representing the ratio of useful output to input.
What of the machine compares the output work to the input work and is expressed as a percent?
That's the machine's "efficiency".
What is B.H.P in 3 phase induction motor?
BHP stands for 'brake horsepower', and simply means it is describing the output, rather than the input, power of the machine. Although a motor's output power is expressed in horsepower in North America, elsewhere it is expressed in watts.
What is a quantity usually expressed as a percentage the measure the ratio of work output to work Input?
Efficiency is a quantity typically expressed as a percentage to measure the ratio of work output to work input. It indicates how effectively a system or process is utilizing energy or resources to produce desired outputs.
When discussing engines the ratio of output work to input work expressed as a percentage is called .?
The ratio of output work to input work expressed as a percentage is called the efficiency of the engine. It measures how well an engine converts fuel energy into useful work output. A higher efficiency indicates that the engine is more effective at converting energy into work.
What do you compare work input to when calculating effieciency?
When calculating efficiency, work input is compared to the work output. Efficiency is the ratio of the work output to the work input, expressed as a percentage. It shows how effectively a system converts input energy into useful output energy.
