When pitot-static tubes are used to measuregas flowvelocitiesequation (1.58)may be acceptable for low flows with low pressure differences. At high velocities thecompressibilitymust be taken into account andequation (1.110)used with stream conditions atXreplacing those at the throatt. ...
According to this equation, the flow of gas is directly proportional to the pressure difference. In a straight cylindrical pipe of radius a and length L, the equation becomes a hydraulic equivalent of Ohm’s law: [6.1.2]QV=ΔPR where R is the equivalent resistance to gas flow through the...
Some of the parameters used to express the hydrodynamic equation usually used to describe the flow of an ideal compressible gas through a nozzle do not lend themselves to easy laboratory measurement, and also the equation is not directly applicable to a normal viscous gas. To circumvent these pro...

Gas specific gravity and molecular weight are related by the following equation:Gas critical pressure ratio (Munson, p. 719; White, p. 609; Daugherty, p. 274):If P3/P1 > (P2/P1)c, the gas flow out of the crack is subsonic and (Daugherty, p. 275; with gas discharge coefficient C ...

including the Knudsen theory and the Boltzmann equation8. The Knudsen theory provides a concise approach to quantitatively describe the gas flow rate9,10. It was first purposed in 1909 by Martin Knudsen and its original formulation is only valid for a long channel with circular cross-section11....
Equation 3 does not take into consideration gas compressibility, mixed phase flow or high pressure drop. Compressibility is considered in Equations 12 and 13. Usable pressure drop for valve sizing calculations for gas, vapor, and steam flows is always limited to half of the absolute inlet pressure...
