STROKE VOLUME(SV) is the volume of blood pumped by ventricle during each contracion/cardiac cycle
SV=END DIASTOLIC VOLUME - END SYSTOLIC VOLUME
EJECTION FRACTION(EF) is the fraction of end diastolic blood pumped by ventriclea during each contraction
EF=SV/EDV
Stroke volume refers to the volume of air that is displaced or compressed by the piston in a single stroke. Swept volume, on the other hand, refers to the total volume that is displaced by the piston over the entire displacement cycle, including the clearance volume. In summary, stroke volume is the volume displaced in one stroke, while swept volume is the total volume displaced throughout the entire cycle.
The amount of compression in a cylinder in an internal combustion engine typically ranges from 8:1 to 12:1. This ratio represents the difference in volume between the cylinder when the piston is at the bottom of its stroke (largest volume) and when it's at the top of its stroke (smallest volume). This compression ratio affects the engine's efficiency and performance.
This rather depends upon whether you are considering either the human heart, or a cylinder in a combustion engine. Though the concepts are roughly similar.In the case of the combustion engine, the stroke volume is bore area x stroke length. In a given engine we cannot increase the stroke, for this is determined by the overall engine design. But the bore of the cylinders can be increased slightly to give a larger volume, and hence a slightly higher output.Another trick is to minimize the 'dead space' at the top of the cylinder, and occasionally, the cylinder head may be slightly planed, and either of these modifications will increase the compression ratio. These modifications can only be undertaken by a person well-informed on engine behavior. And your engine warranty is invalidated.In the case of the human heart, stroke volume is the difference in volume of the heart ventricle, between maximum capacity and minimum capacity. (diastolic volume minus systolic volume.) For an ordinary man this will be in the vicinity of 70mL.This may be increased over time by aerobic exercise. This will often be accompanied by a decrease in resting pulse rate. This may be due to a greater elasticity of the heart muscle, or by an increase of the actual volume of the ventricle itself. Scleroses will have a deleterious effect. Both ventricles will, obviously, have a similar volume.(A very fit friend, had a rest pulse rate of less than 30/min - a cause of momentary concern when he was admitted to ER after a minor work accident!)
The stroke volume in an air compressor is typically calculated using the equation: Stroke Volume = π/4 * Bore^2 * Stroke. Bore represents the diameter of the cylinder and Stroke represents the distance the piston travels in the cylinder during one cycle.
The gas vapor air mixture enters the cylinder during the intake stroke of the four-stroke cycle. This mixture is then compressed during the compression stroke before being ignited by a spark plug, leading to combustion and generation of power during the power stroke. Finally, the exhaust gases are expelled during the exhaust stroke.
Stroke-Volume
Ejection fraction is Stroke Volume/end-diastolic volume. This is a measure of the amount of blood ejected from the left ventricle each beat. Things that can lower this ejection fraction are: Damage to the heart muscle (heartattack) Weak muscle Lack of muscle (dilated cardiomyopathy) Low fluid volume CHF....
There is no thermodynamic difference between them .
The engine, I believe.
No difference.
the raptor is a 4 stroke and the bandanshee is 2 stroke
Ejection fraction is a measure of how much blood your heart is effectively pumping. It's actually the measure of the blood contained in your ventricles when they're full (end diastolic volume nor EDV) and the amount remaining in the ventricles after pumping is entirely completed (end systolic volume). So the jection fraction is the amount of blood pumped divided by the EDV and expressed as a fraction Larger numbers are usually better. 50-60% is healthy.
if you see the difference between valves
the difference is that a kx is a 2 stroke bike and a klx is a four stroke. the difference in strokes is the cylinders and a 2 stroke needs gas mixed with the oil
The difference between 2stroke engines and 4-stroke engines are pretty much the same regardless of where the engine is used. To read about it, check out the related question below.
There is no difference, they mean the same thing.
A 2 stroke has a high pitch sound like a weed eater and a 4 stroke is deeper sound.
