I am usually bad with calculations, so please help me out.
It's not a homework, merely my interest...
So, let's say I have a tube with some air pressure in it and I open up one end of the tube so the pressurised gas exits it in one direction... (basically a rocket)
Pretty simple, huh? :D
But what I want to know is how to calculate the speed of the gas exiting, the thrust, the reaction force etc.
And while we are at it, what if the pressure in the tube is lower than outside, what speed will the outside gas enter the tube, how fast it will fill depending on the size, etc?
Please forgive me asking for such relatively simple calculations. ;)
