CNG Gas Transport Calculator
Calculates deliverable gas volumes for compressed natural gas (CNG) tube trailers and cascade storage systems. Uses real gas law with pressure-dependent Z-factor (Dranchuk-Abou-Kassem correlation) for accurate volume calculations per NFPA 52 and DOT 49 CFR Part 178 standards.
Calculation Mode:
Tube Trailer Parameters
gal
Total cylinder water volume (typical: 6,000-12,000 gal)
psig
CNG standard: 3000-3600 psig
psig
Minimum usable pressure at destination
Virtual Pipeline Logistics
MCF/day
Customer gas consumption rate
hours
Load + travel + unload + return
hours/day
Available trucking hours per day
Cascade Storage System
