1. Engineering Principles & Mathematical Formulation

Calculates velocity gradient G (s⁻¹), detention time, and GT value for rapid mix basins or flocculators based on water temperature, motor power input, and basin volume.

This calculation engine executes rigorous mass-balance and hydraulic equations. Every parameter is cross-checked to ensure zero rounding drift across bidirectional US Imperial and SI Metric unit systems.
