Calculated Theoretical Gas Vol (V₀):
92.0 L (Ideal Gas)
Estimated Nitrogen Precharge (p0 @ T):
144.0 bar (Typical manufacturer recommendation: P₀ = 0.90 × p₁)
Reference Precharge @ 20°C (Cold Fill):
132.6 bar
Temperature Correction Factor (kT):
45°C (kT = 1.085, +8.5%)
Candidate Accumulator Technology:
Candidate: Large Bladder (BAKH Series) or Industrial Piston (HAK Series)
Candidate Shell Pressure Class:
Class 350 bar (35 MPa)
Calculation Basis & Engineering Boundaries:
• Pressure Input: Gauge (bar g).
• Internal Gas-Law Pressure: Absolute (bar abs = bar g + 1.0 bar).
• Atmospheric Approximation: The calculator uses 1.0 bar as the nominal atmospheric-pressure approximation for gauge-to-absolute conversion.
• Application: Energy Storage / Auxiliary Power.
• Precharge Basis: P₁ (Minimum operating pressure).
• Precharge Factor: 0.90 (Typical manufacturer starting guideline: P₀ = 0.90 × P₁).
• Gas Process: Adiabatic Expansion.
• Polytropic Exponent n: 1.40.
• Real-Gas Correction: Not Applied — Preliminary Ideal Estimate.
• Real-Gas Warning: Active (> 200 bar threshold exceeded).
• Temperature Model: Single-temperature preliminary conversion (ref: 20°C). Ambient extremes (Tmin/Tmax) require verification.
• Catalog Mapping: Automated standard selection range (≤ 800 L, ≤ 690 bar). Custom high-pressure piston configurations up to 2,000 bar (200 MPa) and 1,500 L single vessels require engineering review.
