# Industrial Specification: Water Flow Control Valve

## 1. Technical Definition
A valve that regulates water flow rate in a laminar cooling system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15.0 bar differential pressure, 5-95°C water temperature**. Failure boundary: **Cavitation occurs at vapor pressure ≤0.023 bar absolute at 20°C, mechanical failure at 22.5 bar differential pressure**, Mechanism: **Cavitation-induced erosion from localized pressure drops below water vapor pressure, causing implosive bubble collapse with 690 MPa microjet impacts on valve surfaces**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
