# Industrial Specification: Branch Outlet

## 1. Technical Definition
A connection point where a secondary pipeline or duct branches off from a main line within a piping or ducting system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-25 bar (2.5 MPa) pressure differential, -40°C to 150°C temperature range, 0.5-15 m/s fluid velocity**. Failure boundary: **Pressure exceeding 37.5 bar (3.75 MPa) causes material yield, temperature exceeding 200°C initiates creep deformation, velocity exceeding 25 m/s induces erosion-corrosion**, Mechanism: **Stress concentration at branch junction exceeding material yield strength (σ_y = 250 MPa for carbon steel), thermal expansion mismatch (α_main = 11.7×10^-6/°C vs α_branch = 16.5×10^-6/°C for stainless steel), turbulent flow separation causing localized erosion (Wall shear stress &gt; 50 Pa)**.

### 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.
