How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
How do you measure efficiency?
Efficiency= Mechanical Advantage Speed ratio X100 Mechanical advantage divided by speed radio X (times) 100
What is the formula used to calculate mechanical advantage?
Mechanical advantage=load/effort
How does compression ratio affect engine efficiency and performance?
Engine efficiency is increased though compression ratio by allowing a more thermodynamic energy to be converted into mechanical energy. Energy transfer is the key to efficiency.
Why can't a pulley have a mechanical advantage greater than 1?
The mechanical advantage of a pulley can be greater than 1.The efficiency cannot but that is a different matter.
Formula for calculating efficiency of a mechanical system?
Efficiency % = (Output/Input) x 100
What is the formula for calculating efficiency of a mechabical system?
Assuming you meant mechanical, Energy output / Input x 100
What is formula for thermal efficiency?
Thermal Eff = (mechanical heat produced/electrical heat produced) x 100%
What is the mechanical efficiency of a machine that produces 400 jouls of work output from a work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
What is the mechanical efficiency of a machine that produces 400 joules of work output from work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
What is mechanical efficiency in science?
mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.
How do you calculate effort the machine of velocity ratio 5 and efficiency 60 percent calculate the effort required to lift a load of 300N?
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N
Is it possible to find mechanical efficiency of multi-cylinder diesel engine by Morse test?
yes
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
Why do you multiply to find the total mechanical advantage?
The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
What is the mechanical efficiency of a machine that produce 400 joules of work output from a work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
What is formula for mechanical efficiency?
Mechanical efficiency:force x distance (output)/ force x distance (input) x 100%ex. 700n x 2 m / 800n x 2m x 100%1400nm/1600nm x 100%0.875 x 100%= 875Mechanical efficiency= 875%The preceding example is incorrectMechanical efficiency is: % efficiency=output power/input power x 100
