# Industrial Specification: Manifold Distribution Block

## 1. Technical Definition
A precision-engineered component that distributes cryogenic fluid from a single source to multiple outlets within a spray system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-35 MPa (1-350 bar) at 77-293 K (-196°C to 20°C)**. Failure boundary: **38 MPa (380 bar) internal pressure or 343 K (70°C) fluid temperature**, Mechanism: **Yield strength exceedance of 316L stainless steel (205 MPa at 77K) leading to plastic deformation, or phase change-induced thermal stress from LN₂ to LHe transition at 4.2K**.

### 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.
