mechlab 0.2.2

Computational Mechanical Engineering Toolkit

MechLab 🔧📘

MechLab is an open‑source Python library for mechanical engineering computations, designed to provide a unified, modular, and extensible toolkit for students, researchers, and practicing engineers.

It brings together commonly used scientific libraries under a clean, engineering‑focused API for thermodynamics, fluid mechanics, control systems, and numerical analysis.

✨ Features

• 🔥 Thermodynamics utilities (properties, processes, cycles)
• 🌊 Fluid mechanics calculations (dimensionless numbers, flow relations)
• 🎛️ Control systems support
• 🧮 Symbolic & numerical computation
• 📐 Unit‑safe calculations (planned)
• 🧱 Modular structure (easy to extend)

---

📦 Installation

Install directly from PyPI:

pip install mechlab

Or using Poetry:

poetry add mechlab

---

🚀 Quick Start

from mechlab.thermodynamics import enthalpy_TP

h = enthalpy_TP(
    fluid="Water",
    T=500,        # Temperature in K
    P=3e6         # Pressure in Pa
)

print(f"Enthalpy: {h:.2f} J/kg")

🧠 Design Philosophy

• Engineering‑first API (clear variable names, physical meaning)
• Readable code over premature optimization
• Modular – each subject area is independent
• Extensible – easy to add new models & correlations

---

📈 Roadmap

• Rankine, Otto, Diesel cycles
• Pipe flow & heat exchanger modules
• Full unit‑aware API using Pint
• Validation against textbook examples
• Interactive Jupyter examples
