# Industrial Specification: Mixing Hopper/Tank

## 1. Technical Definition
A container designed to receive, hold, and facilitate the mixing of dry and liquid components to form drilling mud.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 MPa internal pressure, 5-60°C operating temperature, 0.5-15 m³ capacity**. Failure boundary: **Material yield strength exceeded at 2.5 MPa internal pressure, structural buckling at 3.0 MPa external pressure, agitator shaft deflection exceeding 0.002×shaft length**, Mechanism: **Von Mises stress exceeding ASTM A240 316L stainless steel yield strength of 205 MPa, Euler buckling instability in cylindrical shell under external pressure, torsional fatigue failure at agitator shaft stress concentration points**.

### 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.
