The mechanical what of a machine compares the input force with the output force?
Mechanical efficiency
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
What is the term for the comparison of input and output work of a machine?
Sounds like you are asking about "mechanical advantage"...
If there was no friction what would that do to mechanical advantage and how would it affect efficiency?
Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.
The amount by which a machine multiplies an input force is called?
mechanical advantage
How theoretically can calculate volumetric efficiency in diesel engines?
1282kg/s
What is the maximum volumetric efficiency of Reciprocating compressor?
if you see volumetric efficiency is compared with the swept volume of compressor without considering the clearance which is normally 5% of the swept volume so you can say 95% is the max. vol. eff
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.
What are two mechanical devices that improve volumetric efficiency?
The supercharger, which uses a belt, driven by the engine, to forcer more air into the intake manifold, and a turbocharger, which uses a turbine driven by exiting exhaust gasses, to do the same thing.
Improvement of Volumetric efficiency in compressor?
More revolutions, more capacity or PORT AND POLISH
What are the causes of reduced volumetric efficiency?
Reduction in power density. Power density is the power produced by the engine per volume unit. Reduced volumetric efficiency means that less air/fuel will be delivered to the engine for a specific engine volume.
What is air turbo charger?
All turbochargers compress air to increase the volumetric efficiency of an engine.
What is the formula to find mechanical efficiency?
Mechanical efficiency = (output energy)/(input energy) . It's typically stated as a percentage.
How do you improve volumetric efficiency?
1>increase the number of valves. 2>make the inlet valve big
Why volumetric efficiency is used in four stroke engines only not for two stroke?
Volumetric efficiency is a figure associated with every engine, 2 stroke, rotary, 6 stroke, etc. it isn't as common to see VE used in 2-stroke topics because most builders these days use figures that are more useful for the tasks at hand. Volumetric efficiency is almost an implied thought or a sub-conscious topic; more of a task than a means.
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
How do you measure efficiency?
Efficiency= Mechanical Advantage Speed ratio X100 Mechanical advantage divided by speed radio X (times) 100
