Choke Calibration (Erosion Check)
Input your Actual Separator Rate to find the true effective choke size.
Effective Diameter Calculation:
$$D_{eff} = 128 \times \sqrt{\frac{Q_{mscf/d} \times \sqrt{T_R \times \gamma_g \times Z}}{\pi \times C \times P_{psia} \times C_d}}$$Erosion & Washout Guide
| Variance | Status | Action Required |
|---|---|---|
| < 1.5/64" | Intact | Normal operations. |
| 1.5 - 3.0 | Worn | Monitor closely for sand production. |
| > 3.0/64" | Washed Out | Switch to standby choke and inspect bean. |
