Restriction Orifice Plate Thickness Calculator

[Weegie]

Would anybody happen to have an (Excel based) RO plate thickness calculator ?
(My work's computer was recently upgraded and I've lost the one that I had.)

Thanks.

You can give a shot to the calculator at the link below (it works on Java) or build another spreasheet following the theoretical explanation reported in the same website

thanks Ione but, not what I'm looking for. I have similar calculators but, I'm looking for a program that will calculate the thickness of the RO plate based a known pressure drop.
If you need a good free down loadable FE/RO calculator
get the DG2floCalLite. It's a great program !

R.W. Miller formula for orifice plate thickness calculation

tmin ? SQRT [(0.681-0.651*BETA)*deltaP/Y] * pipe ID

where


tmin = min plate thickness [mm]
BETA = ratio of orifice hole diameter to pipe diameter
deltaP = pressure drop [MPa]
Y = plate material yield stress [MPa]
Pipe ID = pipe internal diameter [mm]

Ione,

much obliged for the formula.

best regards,
