Professional Engineering Tool with Compressibility Factor Analysis
Formula: V = π/4 × D² × L
Standard cylindrical volume per GPSA Section 17.
• Liquid inventory & batch tracking
• Hydrostatic test water requirements
• Drainage, purging & inerting volumes
• Pig launcher/receiver sizing
• Use actual ID (not nominal pipe size)
• Water density: 62.37 lb/ft³ @ 60°F
• Pig displacement: 95-98% of pipe vol
• Hydrotest: Add 3%/1000 psi compression
• Gas: Sutton + DAK correlations (±1-2%)
• Custody transfer: Use AGA-8 Detail
Understand pipe volume principles, calculations, and industry applications
