# Industrial Specification: Reservoir / Pump Assembly

## 1. Technical Definition
A combined unit consisting of a reservoir and pump that circulates refrigerant within a chiller system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-25 bar (gauge pressure), -20°C to +120°C fluid temperature, 500-3600 RPM pump speed**. Failure boundary: **Cavitation occurs at NPSHa &lt; NPSHr + 0.5 m, bearing failure at &gt;90°C oil temperature, seal failure at &gt;15 bar differential pressure**, Mechanism: **Cavitation due to vapor pressure drop below saturation at 0.023 bar absolute at 20°C refrigerant, bearing fatigue from Hertzian contact stress exceeding 1.8 GPa yield strength**.

### 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.
