Orifice Flow Calculator

Modern Professional Standalone HTML Dry Gas Prototype

Standards target

AGA-3 / AGA-8 / GPA-2172 / GPA-2145

This version focuses on a cleaner presentation and easier field use. The current math remains prototype-level until validated against your approved routines.

Engineering note: This self-contained HTML file is designed for quick browser testing and layout review. It includes composition input, a supercompressibility toggle, and dry-gas orifice workflow, but it is not yet a validated standards engine.

Input Parameters

Enter field conditions, geometry, and either gas gravity or composition.

Implementation Roadmap

Next upgrades for a production version.

• Replace the provisional flow engine with validated AGA-3 routines.
• Replace current composition and Z-factor prototype logic with validated AGA-8 and GPA-2172 / GPA-2145 routines.
• Add save/load calculations and export options.
• Package the same design for iPhone and Android later.
