Description
Erosion velocity analysis using API RP 14E methodology. Calculates erosional velocity limit, actual mixture velocity, erosion ratio, and risk classification for multiphase pipelines.
Parameters:
- rho_g: Gas density at flowing conditions (lb/ft3)
- rho_L: Liquid density (lb/ft3)
- lambda_g: Gas void fraction (0-1)
- Qg: Gas volumetric rate (ft3/s)
- QL: Liquid volumetric rate (ft3/s)
- ID: Pipe internal diameter (in)
- C: API 14E C factor (100 for continuous, 125 for intermittent)
