01 Properties of Fluids

📘 PRISM Engineering Fundamentals Series

Properties of Fluids — From First Principles to CFD

Most engineers learn fluid properties as definitions and equations.

Few understand how these properties influence real engineering systems, CFD simulations, heat transfer, pressure losses, cavitation, and design decisions.

This learning note bridges the gap between academic theory and industrial engineering practice through a structured approach:

Concept → Physics → Equation → Numerical → CFD Interpretation → Engineering Decision
