# Industrial Specification: Hopper

## 1. Technical Definition
A container that holds and dispenses powder materials in a controlled manner.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 bar internal pressure differential**. Failure boundary: **Material yield strength exceeded at 3.5 bar internal pressure differential or 150°C wall temperature**, Mechanism: **Von Mises stress exceeding 250 MPa yield strength of 316L stainless steel at elevated temperatures, causing plastic deformation and material creep**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Electrostatic charge accumulation exceeding 10 mJ ignition energy threshold | 8 | Powder deflagration propagating at 300 m/s through hopper volume | Grounding system maintaining &lt;1.0 MΩ resistance to earth with ionization neutralizers |
| Moisture ingress raising powder moisture content above 5% by weight | 8 | Bridging and rat-holing with 60° angle of repose collapse | Desiccant bed maintaining &lt;30% relative humidity with dew point monitoring at -40°C |

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

### Q: What materials are available for the hopper construction?
**A**: Our hoppers are available in stainless steel for corrosion resistance, carbon steel for durability, and food-grade plastic for sanitary applications in powder handling.

### Q: What components are included in the hopper's bill of materials (BOM)?
**A**: The standard BOM includes an outlet valve for controlled discharge, an agitator to prevent material bridging, and a level sensor to monitor powder volume.

### Q: How does the hopper ensure controlled powder dispensing?
**A**: The combination of outlet valve precision, agitator consistency, and level sensor monitoring allows for accurate, controlled powder dispensing in manufacturing processes.
