Gas Pressure Slide Rule
Equilibrium follows the volume × temperature chart (4–21 °C) with the spreadsheet model outside that band; mixed‑gas uses CO₂ partial‑pressure math; 60/40 is site‑capped at 40 psi by default.

Best practice on reference charts: set applied pressure about 2–3 psi above equilibrium for dispense (long‑draw push is on top of that when you enter it).
