Relates pressure drop on the choke with the flowrate through the choke arising from fluid friction with choke walls:
p_{out} - p_{in} = \frac{\rho}{8.05 \, d^4_D \, C_D^2} \cdot q^2 |
where
fluid density | |
choke diameter | |
choke coefficient (see ) |
C_D = \frac{d_D}{d} + 0.3167 \cdot \left( \frac{d}{d_D} \right)^{0.6} + 0.025 \cdot \big [ \log {\rm Re} - 4 \big ] |
where
internal diameter of the incharge/discharge pipe | |
Reynolds number |
