Abstract
It has been known for some time that when a gas flows through an orifice the coefficient of discharge increases as the ratio of the downstream pressure to the upstream pressure is reduced (Stanton (1)).† This increase continues even after the critical (sonic) pressure ratio is passed, since, unless the discharge coefficient of the orifice is already unity, the mean velocity in the plane of the orifice is still subsonic and can be influenced by the downstream pressure.Keywords
