# Industrial Specification: Feed Tank &amp; Pump

## 1. Technical Definition
A combined unit consisting of a storage tank and pump for feeding solvent into an automated recovery and purification system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-6.0 bar inlet pressure, 1.0-15.0 bar discharge pressure, 5-60°C fluid temperature**. Failure boundary: **NPSHr &gt; NPSHa by 0.3 m, discharge pressure exceeding 17.2 bar, fluid temperature exceeding 80°C**, Mechanism: **Cavitation occurs when net positive suction head available (NPSHa) falls below net positive suction head required (NPSHr) by 0.3 m, causing vapor bubble formation and implosion at pump impeller 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.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| f | Friction Factor | Engineering Constant |
| L | Pipe Length | Engineering Constant |
| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Solvent vapor pressure exceeding NPSHa at 60°C operating temperature | 8 | Cavitation-induced impeller erosion and flow instability | Installation of NPSH margin sensor with automated feed temperature control to maintain ΔNPSH &gt; 0.5 m |
| Polymerization of solvent residues at 70°C tank wall temperature | 8 | Flow restriction and pump seizure from solidified deposits | Integrated tank wall heating control maintaining 45-55°C with automated solvent flush cycle every 72 hours |
