Does an ideal machine would have an efficiency greater than one?
No, an efficiency greater than one would not be possible, since that would violate a very fundamental law of physics: conservation of energy. The efficiency of an "ideal machine" would be one, in many cases; the efficiency of an ideal Carnot engine would be less than one.
Why a high-efficiency machine is more desirable than a low- efficiency machine?
High-efficiency machines do more for less and are therefore more desirable than a low-efficiency machine.AnswerHigher efficiency means lower energy losses and, therefore, such machines are more economical than low-efficiency machines.
What is the relationship between ideal mechanical advantage and velocity ratio?
The ratio of Mechanical Advantage and Velocity Ratio is Efficiency. That is to say the ratio of M.A. and V.R. is constant.
Are 3 gallons greater than 12 quarts?
It is greater than
Can gravity ever be greater than friction?
my dear gravity is forever greater than friction and strong atomic force is greater than gravity
How do you prove that the efficiency C arnot is greater than 1?
You don't. Such an efficiency can be less than 1, but it can't be greater than 1.
Why efficiency of generator is greater than motor?
i think both will be same..

What is more applicable screw type compressor or reciprocating compressor in terms of printing?
A screw air compressor generates greater volumes of air more quickly than that of a conventional air compressor .
Why can't the efficiency of a device or a process be greater than 100?
Efficiency cannot be greater than 100% because efficiency measures energy, and since energy is not made, only transfered (conservation of energy) then we cannot gain energy. Hence the energy out must be at most the energy in. Thus efficiency can be at most 100%
Why efficiency is greater then 1 in case of compound lever?
why efficency is greater than 1 in case of compound lever
Can a machine's efficiency can be greater than 100 percent?
nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as there is some loss of energy is always involved in different ways.
Why is the axial flow compressor better than the centrifugal compressor?
Higher peak volumetric efficiency. You don't have to turn the air at all, so you do not lose and energy in transforming it as you compress the air.
Does bypassing AC compressor on vehicle improve fuel efficiency?
Bypassing the AC compressor will give a slight amount of fuel efficiency to the engine. However on hot days you will be driving with the windows down which is less efficient than using AC, so its a trade off.
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.
How does the isothermal process take place in a air compressor work?
I should say it is closer to Isothermal process when the air in a compressor is cooled in between stages (Of course for multi stage compressor). The cooling brings the work from Adabatic process towards the isothermal process (constant temperature) which increases the efficiency. for more info, check-http://www.marineinsight.com/tech/auxiliary-machinery/efficiency-of-air-compressor-and-uses-of-compressed-air-on-a-ship/
Why do levers have a greater mechanical efficiency than simple machines?
The transmission lever is very simple and there is no friction.
