Where: Re=

For turbulent flows the equation below shows the relation between driving pressure difference and flow rate. Please note that for laminar flows AP is dependent on flow rate V to the power of 1, whereas for turbulent flows AP is dependent on flow rate V to the power of 2. In addition turbulent flows are dependent on gas density.
