Graphical Estimation of Flow through Orifices: Generalized Chart for Estimating Airflow Through Sharp Edged Orifices at Sub‐Critical Pressure Ratios

Abstract

For compressible subsonic flow through a sharp‐edged orifice, where pressures are measured by static pipeline taps, the Saint‐Venant and Wanzel equation for nozzle discharge, applies as follows:
