Formula for calculating efficiency of a power supply?
Efficiency = workout / workin * 100% how do I format this in the worksheet if the workout=KG what the work in will be?
The efficiency of an electric motor is given by the expression?
mu = output power / input power; where mu is the efficiency input power can be calculated from P = IV ; where P is power, I is current, and V is voltage. output power can be calculated from P = Fv ; where P is power, F is applied force, and v is the velocity.
How do you calculate voltage efficinecy in DC voltage?
The efficiency of a device in electronics and electrical engineering is defined as useful power output divided by the total electrical power consumed. Scroll down to related links and look at "Electrical efficiency - Wikipedia".
How do you calculate hp from amps?
1 HP is 746 watts in principle. The power is in watts, and the power is the volts times the amps. For an AC motor the power is the volts times the amps times the power factor times a factor that depends on the power-conversion efficiency of the motor.
How can you calculate the efficiency of an appliance in terms of power?
vague question. Efficiency in terms of energy = useful energy/total energy x 100 vague question. Efficiency in terms of energy = useful energy/total energy x 100
If the power input to a machin 75w and the output is 50w the efficiency is?
Generally efficiency is the ratio of the energy or power utilized usefully to the energy or power given as input to the device. So efficiency in this case = 50/75 = 2/3 Usually efficiency will be given in percentage. So multiplying 2/3 by 100 we get 66.7% as the efficiency of the machine.
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.
What must you know in order to calculate a machine's efficiency?
The efficiency tells you how good the machine is. Efficiency equals the power output of the machine divided by the power that is input via a shaft, or via electrical wires, or via fuel. So if the machine has a low efficiency it wastes power and energy, which costs money. The average ordinary automobile has an efficiency of 20-25%. A lot of research work goes into improving that figure.
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.
Formula for calculating efficiency of a power supply?
Efficiency = workout / workin * 100% how do I format this in the worksheet if the workout=KG what the work in will be?
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.
How do you calculate the efficiency of an electrical mechanical system?
You could have an electric motor driving a reduction gearbox, for example. The efficiencies of both might be considered individually, or as a whole. As a whole is easier. (Work out/ work in) x 100 = efficiency%. Or, (power out/ power in) x 100 = efficiency%. Or, (force out/ force in) x100 = efficiency%. It depends on what you have to work with, what you use. If you did need to calculate electrical and mechanical efficiencies separately because of different units, the final overall efficiency will be (total of the percentages) / (number of percentages).
The efficiency of an electric motor is given by the expression?
mu = output power / input power; where mu is the efficiency input power can be calculated from P = IV ; where P is power, I is current, and V is voltage. output power can be calculated from P = Fv ; where P is power, F is applied force, and v is the velocity.
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 ?
How do you calculate voltage efficinecy in DC voltage?
The efficiency of a device in electronics and electrical engineering is defined as useful power output divided by the total electrical power consumed. Scroll down to related links and look at "Electrical efficiency - Wikipedia".
Efficiency is a comparison of?
Efficiency is output power divide by input power.
What is the efficiency of hydraulic generators?
Basically, you need to calculate the amount of energy contained in the fuel you use to produce a given amount of electrical energy. To calculate the amount of energy in the fuel you need to lookup the number of thermal energy units per unit volume then you can convert those thermal energy units into Joules (1 gallon [U.S.] of diesel oil = 146 520 000 joules - www.onlineconversion.com) The on the electrical side, just multiply the voltage by the current by the number of seconds of run time (unvarying load) to get the electrical power output in Joules. Then the efficiency is just the the output power divided by the input power (x100 for %).
