Ronj is going on about a "plumb," he must have pulled out with his thumb over in a corner somewhere. Conveniently forgetting that no "plumb," assigns a big fat 0 to the A in the equation. I don't care if you multiply 1,000,000 M's to the big fat 0 of A, F will end up as a big fat 0.
Donutz is still asking how jets move when he is supposedly a former jet engine mechanic (by the way my nephew is currently employed by United Airlines, having served over 10 years as a former Air Force jet engine mechanic). Jets too, form a plume in the pressurized atmoplane, allowing them to move. The only difference in accomplishing their operation of movement is jets require an intake of external oxygen to achieve combustion (open system), whereas rockets do not have air intakes and have a self-contained material allowing combustion to take place when it is mixed with the fuel.
And faker is going on about who is ill-prepared, when his lack of reasoning has been so thoroughly discredited on this site it is laughable.
You are the one, faker, who was posting the bounce-around terms, clearly subscribing to them, just willy-nilly all over the place.
Really laughable.
Typical.
Rockets work in a pressurized environment where they can form a plume.
No external pressure outside the rocket?
No plume.
No plume?
No movement.
The end.
