DevinStroke volume is the amount of blood pumped out by the heart with each beat, while ejection fraction is the percentage of blood pumped out of the heart with each contraction. Stroke volume is a measure of the quantity of blood pumped, while ejection fraction is a measure of the efficiency of the heart in pumping blood.

What is the difference between stroke volume and swept volume in air compressor?
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.
How much compression per cyinder?
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.
What are the factors that would increase stroke volume?
Factors that can increase stroke volume include increased preload (end diastolic volume), increased contractility of the heart muscle, decreased afterload (resistance to ejection of blood), and a higher heart rate. Adequate hydration, regular exercise, and a healthy diet can also support optimal stroke volume.
What is the equation for the stroke volume in air compressor?
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.
In an internal combustion engine the gas vapor air mixture enters the cylinder during the stroke?
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.
