The Best Orifice Type for highest pressure drop

[theo1234901]

I'm an engineering student, one of my task is to search the best orifice type for pressure drop. I have no idea which one would it be since I believe that the beta ratio is the one that would determine the best orifice for pressure drop.

The beta ratio is one indicator but the orifice coefficient (ratio of the actual orifice flow to the flow of an ideal orifice) based upon the shape of the orifice is also factor.

what will be the best orifice shape for pressure drop? and would you mind telling me why would that be the best shape for pressure drop?

A quick review of sections 2 and 3 of the below should explain both.
