There are at least six flow regimes to explain the characteristics of the gas flow, such as molecular flow (also called free molecular flow) ; continuum flow including viscous laminar flow, turbulent flow, critical flow (sonic flow or choked flow), and subcritical flow (subsonic flow or non-choked flow) ; and their intermediates (intermediate flow, transition flow, or slip flow). This review paper summarized equations to calculate the gas flow rate through a cylindrical tube for each flow regime.Read More
