Gas velocities from 2 to 4.5 kilometers per second can be obtained in rocket nozzles.

note : thats slightly faster than the speed of sound
wouldnt you say?
speed of sound 340 meters per second.


You've added this since my last reply - trying to sneak stuff through, are we?

You need to go back and read what I've written before - it is the nozzle of the rocket that allows for the gas to be accelerated faster than sound. I said that clearly, on several occasions now.

It is that acceleration that creates Ve.

So bascially, you just supported my argument - you need a divergent nozzle to get faster-than-sound traveling air.

as you can see the Pe-Pa is just the calculatable part of the moveable nozzle.


And once again paul shows he doesn't even read his own sources. Even your own source confirms Pe-Pa is the pressure force, not the force due to nozzle acceleration.

LOL, your own sources showing you to be wrong. Funny!
