And yet are completely unable to provide one iota of proof. Strange, isn't it - you're right and yet you've been able to convince no one here...LOL

And now you're lying - I've repetitively stated the mass of air has velocity upon exiting the tank. If you re-read my last few posts I've even given the exact speed it will move at - the speed of sound.

Odd, that you have to lie about my claims, in order to make your "point".

Nope. And once again the irony - both the page I linked to, as well as the one you linked to, clearly state how nozzles help provide additional thrust. Apparently you don't even read your own sources.

You're wrong here, as has been pointed out time and time again. Ignoring reality doesn't make it go away.

how m*Ve is calculated is broadly published. You ignore those formula, that doesn't make you right.

Wow, the ignorance grows:
1) Jet engines work on a completely different concept. Ergo, not comparable to simple rocket engines

2) The combustion produces pressure. A nozzle is useless without pressure.

No increase in exhaust velocity, therefore m*Ve is zero. There will be the velocity intrinsic to [Pt-Pe]Ae.

Nope, and if that is what you think than you completely missed the point. The fact you think guns and rockets work on the same principals is particularity telling...

So there ya'll have it - Pauls argument in a nut shell:
a) ignore basic physics,
b) re-write formulas to suit his purposes,
c) lie about the claims of others, and
d) come up with irrelevant examples
