Single-Phase Liquid Pipe Flow
Calculate pressure drop for single-phase liquid flow in pipes using the Fanning equation. Applicable to water injection, water disposal, and single-phase oil lines.
Tubing Size Selection Analysis
Compare pressure drops across different tubing sizes to optimize well production. Smaller tubing increases friction but maintains velocity for liquid lift; larger tubing reduces friction but may cause liquid loading in gas wells.
