ABSTRACT:
An orifice plate for use in a conduit through which fluid flows is defined by a central circular region having a radius R0and a ring-shaped region surrounding the central circular region. The ring-shaped region has holes formed therethrough with those holes centered at each radius R thereof satisfying a relationshipin-line-formulae description="In-line Formulae" end="lead"?AR=a/(XRVRb)in-line-formulae description="In-line Formulae" end="tail"?whereARis a sum of areas of those holes having centers at radius R,XRis a flow coefficient at radius R,VRis a velocity of the fluid that is to flow through the conduit at radius R,b is a constant selected to make at least one process variable (associated with the fluid that is to flow through the conduit) approximately equal at each radius R, anda is a constant that is equal to (XRARVRb) at each radius R.
