WebOrifice equation. Edit. The orifice equation describes the rate of flow of liquid through an orifice. The equation can be represented as: where Q = flow (cubic metres per second) = coefficient of discharge. A = area of orifice (square metres) g = acceleration from gravity (9.81 m/s^2) h = head acting on the centreline (m)? WebThe orifice calculator is based on eq. 5 and can be used to calculate mass flow through an orifice. c d - discharge coefficient. D 2 - orifice diameter (m) D 1 - pipe diameter (m) p 1 - upstream pressure (Pa) p 2 - downstream pressure (Pa) ρ - density of fluid (kg/m 3) Typical Orifice K v Values

WebParker's Orifice Fittings come in both 37° flare and O-ring face seal (ORFS) configurations. These compact and cost effective orifice fittings allow OEMs to pre-set, at the factory, a … WebThe flow rate through the orifice is proportional to the orifice opening and to the pressure differential across the orifice. The flow rate is determined according to the following equations: q = C D ⋅ A ( h) 2 ρ Δ p ( Δ p 2 + p Cr 2) 1 / 4, Δ p = p A − p B, h = x 0 + x · o r. A ( h) = { A l e a k if b ⋅ h < A l e a k b ⋅ h otherwise.
