## What is TrimixBlending?

This app allows technical divers to create custom Trimix blends (Helium, Oxygen, Nitrogen) using partial pressure blending (PPB), with support for Nitrox top-ups and ideal gas law calculations for precise gas mixing.

Two models of calculations:
1. Real Gas Calculations, uses equations of state (Van der Waals) for accurate blending. Accounts for molecular interactions and non-ideal behavior
2. Ideal Gas Calculations, uses simple ideal gas law (PV=nRT) and assumes no molecular interactions. Valid for low pressures and high temperatures

Gas Blending Options: Air Blending, Nitrox Blending and Trimix Blending, Continuous blending calculations for Ideal Gasses

Input Validation: Pressure range checking, Oxygen percentage limits, Gas compatibility checking
