Thought I might add...as I've been thinking about it...depending on the stiffness of the materials, if this is considered a constant pressure application, then mean rad would just be: \frac{2}{3} ( \frac{ (r_1^3-r_2^3) }{ (r_1^2-r_2^2) } ) ...regardless of hole pattern...I think.

Hello all, I am trying to remember (I did it in Uni) how to calculate the effective mean radius of an annulus that contains a pattern of holes on a PCD. Consider the following image (pinched from: https://www.solenoid-valves.com/ ): If one was to vary the value of PCD, then the effective...
