How does spooling improve efficiency of an os?
a lot
Levers have a greater mechanical efficiency that other simple machines because?
They have to overcome less friction
Explain efficiency and how to calculate it for different simple machines?
Efficiency means to calculate that is the machine is efficient enough to save your bill or use less electricity. To calculate the formula is:Efficiency = Energy output (what is the machine producing) divided by Energy input (what is the machine taking or using).
What another word for ergonomics?
comfort design, functional design, human factors, user-friendly systems, workplace efficiency.
Is a electric motor a simple machine?
yes
What is motor efficiency?
80%
Difference between eff1 and eff 2 motors?
EFF1 is a high efficiency motor. EFF2 is a standard efficiency motor.
A motor produces less mechanical energy than the energy it uses because the motor what?
Yes this is what we call efficiency of the motor. We give 100 but the motor in turn gives 40, so its efficiency is 40%
What motor is used in sprinkler irrigation systems?
Motor size depends upon number of factore. 1- flow of pupm 2- required head 3- efficiency of pupm used 4- efficiency of electric motor used The formula is H.P required= Q.H\ 3960. Pump efficiency. Motor efficiency where Q= GPM H= Ft Efficiency= In fraction( 70 % = 0.7) Engr. Usman Khalid +923336901945 usman.engr87@gmail.com
Efficiency of motor?
I measure the efficiency of an internal combustian engine by doing (bhp)/((displacement)*(rpm))
When is efficiency of 3phased Induction motor maximum what is the condtion for maximum efficiency in induction motor?
It is maximum at about 75% to 100% of the motor rated load. Efficiency is maximum at unity power factor , when R=X and when variable losses Is equal to constant losses at rated load.
Which motor is superior in efficiency and the most extensively used of all types of electric motors?
Motor efficiency depends on the motor size and how much it is loaded. You get the best efficiency above 75% of the rated load for that motor. Note the table below: Horsepower Standard Premium Efficiency Efficiency% Efficiency% 1 --- 78.0 --- 82.5 2 --- 78.5 --- 84.0 5 --- 84.0 --- 89.6 10 --- 84.0 --- 91.1 15 --- 87.5 --- 91.7 25 --- 90.2 --- 93.0 50 --- 91.7 --- 94.1 100 --- 91.7 --- 95.0 250 --- 94.1 --- 95.8
How much energy does a motor convert to heat?
You can calculate the quantity of energy that a motor turns into heat with either one of these equations: Heat energy = ( 1 - efficiency of the motor) x (energy input to the motor) or Heat energy = ( 1 - efficiency of the motor) x (power input to the motor) x (running time)
What are high efficiency motors?
The efficiency of a motor is the output power divided by the input power. The difference is the lost power which appears as heat usually. High-efficiency motors produce very little lost power. But they tend to be more massive and expensive to make, so that most motor designs have to compromise on efficiency.
Is your power into motor equal to your power out of motor at no load?
For a motor's output power to equal its input power, the motor's efficiency must be 100%. As no machine, particularly a rotating machine, can possibly achieve 100% efficiency, there is no condition under which its output power can ever match its input power.
Why efficiency of generator is greater than motor?
i think both will be same..
What is the efficiency of a motor that has an output of 373 watts with an input of 450 watts?
such a motor would be theoretically 82.8888% efficient
