Capacity coefficient of valves in gas processing

Input(s)

q: Flow Rate $(\mathrm{bbl} / \mathrm{m})$

$\gamma$ : Fluid Relative Density (dimensionless)

P: Pressure Drop (psi)

$\mathrm{C}_{\mathrm{v}}$ : Capacity Coefficient (dimensionless)

\mathrm{C}_{\mathrm{v}}=\left(\frac{\mathrm{q}}{\mathrm{A}}\right) *\left(\frac{\gamma}{\mathrm{P}}\right)^{0.5}
