Abstract
The results of a systematic experimental investigation of compressible flows through rectangular orifices, in particular the effects of the variables transverse length/height, a/b, and axial length/equivalent diameter, l/de, are presented and discussed. Non-monotonic changes in the mass flow rates due to changes in these variables are revealed by normalization using circular orifice data allowing the experimental results to be interpolated over a continuum of each of variables, namely, 1≤a/b≤300 and 03≤ l/de<<3.0. A universal prediction for circular orifices is also given.
