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
This calculator determines internal pipe volume and gas line pack capacity. It computes the total volume of fluid contained within a pipeline segment based on internal diameter and length, using AGA-8 simplified compressibility.
Line pack is the total inventory of gas stored within a pipeline at operating conditions. It depends on pipe volume, operating pressure, temperature, and gas compressibility factor. Line pack is critical for managing supply-demand imbalances.
Internal pipe volume is calculated as V = π/4 × ID² × L, where ID is the internal diameter and L is the pipe length. The calculator converts between various units and accounts for pipe schedule dimensions per ASME B36.10M.
