Jun 2, 2004 · choked or not, the critical issue is the density flowing through the exit area and the thoughest to estimate(two phase flow is likely). you may be restricted to comparing several …

Oct 14, 2003 · This situation is referred to as "choked flow". If when the downstream absolute pressure divided by the upstream pressure is equal to or less than a number that …

Oct 5, 2009 · The adjective “choked” (IMO) should be more properly referred to a particular fluid velocity than to flow (mass) as this condition defines an upper limit for the velocity and not for …

Apr 23, 2008 · In isentropic flow (adiabatic + small friction loss), just as isothermal flow, the mass velocity reaches a maximum when the downstream pressure drops to the point where the …

Dec 16, 2008 · From what I see on the threads you speak of, the difference is that choked flow is when no more flow will go through your valve when decreasing the downstream pressure, with …

May 19, 2016 · "Choked flow" is not a concept in liquid flow, only gas flow. There is a special case where in a converging nozzle pressure in a liquid drops low enough to flash the liquid to vapor, …

Jan 19, 2005 · Choked flow is also referred to as critical flow or sonic flow when the velocity of the fluid reaches its limiting velocity which is the velocity of sound in the flowing fluid at that …

Oct 2, 2002 · (c) Increasing the PSV size further, still increases the flow and the pressure before the outlet choke point increases. (d) Increasing the PSV size even further, will increase the …

Jul 27, 2005 · israelkk is absolutely right. You've got Choked Flow on your hands since 99% of all compressible flow has a P2/P1 ratio greater than 2 - with the only exception possibly being the …

Apr 16, 2007 · "Choked" implies that the flow experienced is less than the flow predicted by the Cv equation. When the flow measured is 2% less than predicted by the Cv equation, it is said …
