The Poiseuille Equation quantifi es the relationship between pressure drop and fl ow. In its simplifi ed form (Equation 2), K is a constant factor determined by the geometry of the restriction. It shows the linear relationship between volumetric fl ow rate (Q), differential pressure (ÄP), and absolute viscosity (ç). To use the Poiseuille...

Additional measurements and calculations are incorporated to determine the actual mass fl ow rate of the gas. Ideal gas laws show us that the density of a gas is affected by its temperature and absolute pressure. Using ideal gas laws requires a reference to a standard temperature and pressure (STP) condition for “normalizing”...
