1. RE: large runner 1500 (single ZS) manifold needed (longish) (score: 1): Author: "Jack W. Drews" <vinttr4@geneseo.net>; Date: Sat, 04 Dec 2004 10:51:31 -0600; Pardon my ignorance, but why would you use such high pressure differentials to flow a head ? Wouldn't just a few inches of water be more similar to actual conditions ? Seems like you'd want the valve; /html/fot/2004-12/msg00034.html (11,276 bytes)

For fully developed tubulent flow, the flow is proportional to the square root of the pressure drop, so it is easy to convert from one pressure drop to another.; /html/fot/2004-12/msg00042.html (9,100 bytes)

At the point where it changes, there should be a fairly big discontinuity in flow rate, no? Avoiding turbulence is the whole reason w; /html/fot/2004-12/msg00043.html (8,276 bytes)

So you could avoid seeing what the problems are? In practical terms, most flowbenches don't flow enough with heads that have reasonably lar; /html/fot/2004-12/msg00045.html (9,760 bytes)

It's a mental picture issue. We view these systems as having smooth flows when in reality everything that's going on in an engine is violent and fast.
