This equation...Not sure what you are talking about. This equation is true for a knife edged orifice. The flow across the orifice must be "turbulent" not "laminar".<br /><br />Your statement "You are assuming/estimating that constant k is the same all throughout downstream." makes no sense to me.JDKhttps://www.blogger.com/profile/16796281957964741569noreply@blogger.comtag:blogger.com,1999:blog-4315911668447344547.post-75161072282354005362009-11-26T10:36:10.142-08:002009-11-26T10:36:10.142-08:00That applies not only a sharp edge orifice, it app...That applies not only a sharp edge orifice, it applies to any orifice as a general equation where k=Q/sqrt deltaP. You are assuming/estimating that constant k is the same all throughout downstream. If two flow controls are in series, I guess k will vary at every orifice point.Anonymousnoreply@blogger.com
