Yea, I am aware of this method but concern is with the coefficeint Cc. Usually an approximation would be good enough and 0.61 to 0.64 usually does the trick. My issue is I am trying to develop a method for calculating a value of noise in orifice plates. approximating Cc isn't a reliable method...

Hi, does anybody know how to find the diameter of the vena contracta in gas/vapour flows in orifice plates?

My employer has asked me to derive a method or equation for determining noise (in decibels) in orifice flow meters. I was wondering if anyone has any suggestions that could help me get on my way? I've been looking at basic principles of aerodynamic and hydrodynamic noise predicitions. As far as...
