# Industrial Specification: Storage Hopper

## 1. Technical Definition
A container component in the Alloy Feeder System designed to temporarily store and regulate the flow of alloy materials before feeding into downstream processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 bar internal pressure, 20-80°C material temperature, 0.1-5.0 m³ material volume**. Failure boundary: **Material bridging at 45° hopper wall angle, structural failure at 4.2 bar internal pressure, flow cessation at 70% material compaction density**, Mechanism: **Janssen effect causing arching at critical wall friction angle, von Mises yield criterion exceeding 250 MPa at pressure vessel seams, particle interlocking at 0.7 packing fraction**.

### 2.1 Analytical Physics Model
Governed by the **Frame Structural Deflection Analysis**:

> **Primary Equation**: $\delta = \frac{5 q L^4}{384 E I}$  
> **Engineering Impact**: Ensures structural stability for multi-stage machines.
