The formula for Thick-Edge Orifice

  1. Aug 16, 2017 #1
    Hi all,

    I have some problem in my research about the thick-edge orifice formula. I can't find the influence of orifice length to the discharge.
    I have found an online calculator for it but I can't find the formula derivation. Anybody can help me? Anybody have recommended literature?

    The website for the online-calculator:

    I recommend you Google "orifice thickness to diameter ratio" where you will find some sources that address your subject
