# Industrial Specification: Agitation System

## 1. Technical Definition
A mechanical subsystem within an automated fermentation control system designed to mix and homogenize fermentation media through controlled agitation.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-5.0 m/s impeller tip speed at 20-200 RPM**. Failure boundary: **Reynolds number &lt; 2000 (laminar flow regime) or impeller tip speed &gt; 7.5 m/s**, Mechanism: **Fluid shear stress exceeding 50 Pa causes cell damage; cavitation occurs at vapor pressure &lt; 0.023 bar absolute**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.

| Symbol | Variable Definition | Localized Reference |
