1. Engineering Principles & Mathematical Formulation

Calculates active mass chemical feed requirements, raw liquid product demand, and dosing metering pump flow rates based on target mg/L dose, plant flow rate, liquid product purity, and specific gravity.

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.
