Abstract
An investigation was made to discover the flow rates of air through sharp-edged orifices in which the pressure drop was below the critical; the relationship of pressure, temperature, and orifice area; and a comparison between the nozzle and the orifice. Equations are derived for expressing orifice flow in both the critical and subcritical regions.Keywords
