Jun 16, 2008 Thread starter #3 Enkidu Mechanical May 13, 2006 17 Thanks Chief. curious - what's the 0.6? bushing width? regards Upvote 0 Downvote
Jun 22, 2008 #4 chief Marine/Ocean Dec 30, 1999 276 The 0.6 is a constant K, depending on the width and shape of the orifice /throat.In this case I surmise the throat is a simple drilled thru' opening. Offshore Engineering&Design Upvote 0 Downvote

Jun 27, 2008 #5 texanman Mechanical May 21, 2008 37 The flow coefficient K, can have a range of .5 to .85 depending on the hole geometry. However 0.6 is a good guess. Upvote 0 Downvote

Jun 27, 2008 #6 texanman Mechanical May 21, 2008 37 Flow coefficient K, can actually have wide range. But 0.65 is a good guess for a sharp hole flow restrictor. It is determined impirically. Upvote 0 Downvote
