# Industrial Specification: Water Pump

## 1. Technical Definition
A mechanical device that circulates coolant through a water cooling system by converting rotational energy into hydraulic energy.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-8.0 bar differential pressure, 5-95°C coolant temperature, 500-3500 RPM shaft speed**. Failure boundary: **Cavitation occurs at NPSHa &lt; NPSHr + 0.5 m, bearing failure at &gt;120°C lubricant temperature, seal failure at &gt;10 bar differential pressure**, Mechanism: **Cavitation-induced pitting from vapor bubble collapse at low NPSH, bearing thermal degradation from lubricant breakdown at Arrhenius rate constant k=1.2×10⁻⁴ s⁻¹, mechanical seal face wear from abrasive particles &gt;25 μm**.

### 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.
