How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
The ratio output power to input power in percent is called?
B. Efficiency
What is the formula to find mechanical efficiency?
Mechanical efficiency = (output energy)/(input energy) . It's typically stated as a percentage.
What is the efficiency is the output work is 12000 and the input work is 15000?
Efficiency as a percent is output/input * 100%12000/15000 * 100% = 80% efficiency which makes sense, because it takes more work (input) than it give out (output). So the efficiency should be less than 100%.
What is the equation for calculating efficiency?
Efficiency is typically calculated using the equation: [ \text{Efficiency} (%) = \left( \frac{\text{Useful Output}}{\text{Total Input}} \right) \times 100 ] This formula measures the ratio of useful work or output generated to the total energy or input consumed, expressed as a percentage. Higher efficiency values indicate more effective use of resources.
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 formula for the percent efficiency of a pulley?
The formula for the percent efficiency of a pulley is (output work/input work) x 100%. It compares the output work (work done by the pulley) to the input work (work done on the pulley) to determine how efficient the pulley system is in transferring energy.
What is the formula to finding the work output of efficiency?
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
What is the efficiency of most power plants?
Light water nuclear plants like PWR and BWR have efficiency of about 33 percent, that is the ratio of electric output to reactor thermal output. Gas cooled reactors can be up to 40 percent as they work at higher temperature.
What is the formula for efficiency?
Output/Input * 100= %
What is the output work of a machine when its efficiency is 62 percent and the input is 39 J?
To calculate the output work of a machine, you can use the formula: Efficiency = (Output Work / Input Work) * 100%. Given that the efficiency is 62% and the input work is 39 J, you can rearrange the formula to solve for the output work. First, convert the efficiency to a decimal (62% = 0.62) and then plug in the values to find the output work. The output work of the machine would be 24.18 J.
What is the formula to efficiency?
Efficiency = (output power/input power) x 100%
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
The efficiency of a ramp is 75 percent If the amount of work input is 240 J what is the amoun t of useful work output?
The formula for percent work efficiency is: percent efficiency = (work output/work input) x 100 To find the answer to this question, you just need to plug the given values into the formula. The problem tells you that the work input is 240 J and the percent efficiency is 75 %, so 75 = (work output/240) x 100 Now, solve for work output: -first divide by 100 .75 = (work output/240) -then multiply by 240 180 J = work output (in units of joules because work is measured in joules) And there's your answer. Hope this helped!
What is the formula for calculating the efficiency of a heat pump?
The formula for calculating the efficiency of a heat pump is the ratio of the heat output to the energy input, expressed as a percentage. It can be calculated using the formula: Efficiency (Heat Output / Energy Input) x 100.
Formula for calculating efficiency of a mechanical system?
Efficiency % = (Output/Input) x 100
What is the efficiency formula of lever?
The efficiency of a lever can be calculated using the formula: Efficiency = (output force × output distance) / (input force × input distance) * 100%. It represents the ratio of the output work done by the lever compared to the input work applied to the lever.
