Description
Gas lift valve throughput calculations using the Thornhill-Craver equation. Determines gas flow rate through an orifice valve based on port size and pressure differential.
Parameters:
- Cd: Discharge coefficient (typically 0.6-0.9)
- Ap: Port area (in²)
- P1: Upstream (casing) pressure (psia)
- P2: Downstream (tubing) pressure (psia)
- SG: Gas specific gravity (air = 1.0)
- T: Gas temperature (°R)
