Talk:Velocity stack
From Wikipedia, the free encyclopedia
"Plane pipe" ...I think you meant "Plain pipe", no?--Hooperbloob 00:27, 24 October 2006 (UTC)
Quite right THANKS!--=Motorhead 01:55, 24 October 2006 (UTC)
How could velocity be improved on a stack? Would a cone at the centre..similar to a ramjet improve it?
No it is already so efficient that anything else might hurt it. The point is not velocity at all, it is smooth even flow into the pipe.Flow in supersonic systems is nothing like flow below the speed of sound. Ramjets run under completely different conditions.--=Motorhead 01:22, 29 November 2006 (UTC)
- 2 "Slightly modify... duration of pulses within the tract." doesn't sound right, is probably poorly worded for your intention. If it is correct, please offer references. Tim S. 10/19/07
It is correct. If you take the entire sentence, it explains how the shape of the bell resembles a reverse megaphone thereby extending any wave passing throught it in either direction, however because it is short its effect will be slight but noticible.--=Motorhead 13:47, 21 October 2007 (UTC)
