EXPERIMENTS on the rapid discharge of gases from cylinders show marked deviations from the accepted quasi‐steady theory. Agreement between experiment and calculation is obtained at the cost of assuming very large coefficients of discharge. It is shown in the present paper, that the discrepancies are due to the fact that the mass discharge is larger than that implied by the quasi‐steady theory, mainly owing to the omission of the considerable velocity of approach. The application of the wave theory of gas mechanics to the case of rapid discharge is sketched and it is shown that the deviations from the quasi‐steady theory predicted by it are of the same order of magnitude, as found experimentally.
