WebMar 13, 2024 · large enough to generate choked flow, that (1) the mass flow rate of a gas through an orifice is proportional to throat area and tank pressure and (2) flow rate does not depend on downstream pressure. Two Models of Tank Blowdown . Eq. 10 gives the rate of mass loss from a tank at a given gas density and temperature. To WebThe gas flow through the orifice is dependent on the orifice diameter, inlet pressure, temperature and the specific gravity of the gas. The size of ori-fices commonly ranges from 0.006 to 0.16 inches (0.15 to 4 mm) in diameter. The orifice needs to allow adequate flow for normal operations, even at lower cylinder pressures, and at the same time
