# Industrial Specification: Impeller/Roller Cell

## 1. Technical Definition
A key rotating component within a fuel pump that creates pressure and moves fuel.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15 bar differential pressure**. Failure boundary: **Cavitation occurs at vapor pressure threshold of 0.0313 bar absolute (fuel vapor pressure at 20°C), material fatigue failure at 10^7 cycles with stress amplitude exceeding 350 MPa**, Mechanism: **Cavitation-induced pitting from localized pressure drops below fuel vapor pressure, leading to surface erosion and material loss; high-cycle fatigue from alternating stresses exceeding S-N curve endurance limit**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
