WebThe table given below gives the discharge of air through an orifice in cu. ft. of free Air per minute at atmospheric Pressure of 14.7 psia, and 70 °F Based on 100% coefficient of flow. For well-rounded entrance multiply values by 0.97. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases. A little downstream of the orifice the flow reaches its point of maximum convergence, the vena contracta (see drawing to the right) where the velocity reache…
