Re: Calculate the Cd of an orifice plate before using.

Ok, thank you. Unfortunately this does not answer my question. It now seems to me that we have a problem when trying to work out the Cd when we go to thicker plates. I'm trying to find out what would happen with changes to plate thickness.. Its seems all these calculations assume that we have a thin...

Re: Calculate the Cd of an orifice plate before using.

Thank you for that but the calculator does not take into account the thickness of the orifice plate, nor the type of edge that is being used. That's what I'm inquiring about If: D1 = 5 inchs D2 = 1 inch P1 = 28 inH20 P2= 16 inH20 Then we get a Cd of .59862 But what happens if the Orifice plate is no...

Calculate the Cd of an orifice plate before using.

Ok I'd like to know how to calculate the approximate coefficient of discharge of an orifice plate flowing air, depending on the type of orifice (in this case straight edged ) and the thickness of the plate. Most sharp edged ones seem to be about .60 to .62 Cd. But I want to use a straight edged so I...
