## Homework Statement

My problem- I have a cylinder of a specific value. One end of the cylinder has a piston and the other end is restricted by a nozzle that is attached to a tube. The information I need is how the flow out the smaller nozzle is effected by the movement of the piston.

## Homework Equations

The equations I know I will need is the force the spring applies on the piston and the velocity of the piston as it moves forward. I know in life that friction form the pistons and the cylinder wall would be an issue as well, but for this exercise I get to ignore that.

I don't know if it is important but the gas in question is ambient air. So if needed I will be using the basic average air mixture at sea level at average tempature.

## The Attempt at a Solution

This is where I get stuck. I do not have a strong physics background as of yet. From my research and questions I have gotten answered by my local professors I will need to understand the continuity principle of fluid. I also believe that I will need to know bernoulli's principle equation. Or perhaps the main equation found here http://www.air-dispersion.com/usource.html

Also I have not provided actual values for the problem because at this stage I am looking for the formulas and understanding on how to apply said formulas.

Anyway, I hope I did this correctly and I hope you guys can assist me. Thanks in advance!
