# Industrial Specification: Water Tank

## 1. Technical Definition
A container that stores water for evaporation in a humidifier.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-2 bar gauge pressure, 5-60°C water temperature**. Failure boundary: **Plastic deformation at 2.5 bar internal pressure, brittle fracture at -10°C water temperature**, Mechanism: **Yield strength exceedance (HDPE: 26 MPa yield strength), ductile-to-brittle transition temperature (HDPE: -20°C transition)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Calcium carbonate scaling exceeding 3 mm thickness | 8 | Reduced heat transfer efficiency by 40%, increased pump head requirement | Integrated ultrasonic descaling system with 28 kHz transducers |
| Polymer chain scission from 254 nm UV-C exposure exceeding 1000 hours | 8 | Material embrittlement with 60% reduction in impact strength | Carbon black additive at 2.5% concentration for UV stabilization |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
| :--- | :--- | :--- | :--- |
| spec | Config-dependent | L | Verified |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are recommended for water tanks in electrical equipment humidifiers?
**A**: Food-grade plastic materials like PP or ABS, or stainless steel, are recommended for corrosion resistance and safety in humidifier applications.

### Q: How does the water level indicator work in these tanks?
**A**: The water level indicator typically uses a transparent section or float gauge to visually monitor water levels, ensuring proper humidifier operation.

### Q: Why is a sealing surface important for humidifier water tanks?
**A**: A proper sealing surface prevents leaks and maintains consistent humidity levels, protecting sensitive electrical equipment from moisture damage.
