This paper describes in detail some investigations relating to shock tube orifice flow experiments and its model calculations. The accuracy of the analytical results of the model has been checked by shock tube experiments. In addition, this model results are also compared with the steady flow data namely, ASME Tap relations and existing data relating to supercritical flow regime. The following results are obtained : (1) The pressure loss of orifice can be well estimated by our model calculations. (2) The agreement of compressible flow coefficients between shock tube model calculations and steady flow data is seen in both cases of subsonic and supercritical flow regimes. (3) These results hold not only for κ ( : ratio of specific heats) =1.4 (air) but also for other gases.
