Witrynad = orifice diameter (m) ρ = fluid density upstream the orifice plate (kg/m3) ΔP = pressure drop through the orifice plate (Pa) The expansibility factor, for gases, can be calculated thanks to the following formula : With : ε = expansibility factor (for gas only, for liquid epsilon = 1) β = d/D p 1 = upstream pressure (Pa) WitrynaISO5167 standard The multi-holes orifice plate is a non-standardized flow element but is designed and manufactured according to ISO5167 standard requirements. The sizing of multi-holes orifice plates is achieved in our design office with the same software as the one used for sharp-edge orifice plates in compliance with the ISO5167 standard. tips for nap training 4 month old baby
