Yuan's Foundations of Fluid Mechanics is currently out of print, but its copyright is likely still active as of its original publication year (1967). While a free PDF may not be legally available for download from public sites, there are several legitimate avenues to access the book:
The text covers the essential foundations required for both undergraduate and postgraduate engineering studies:
By the final pages, Yuan’s voice blended rigor with intuition. Lina closed the book hearing fluids as living systems—governed by conservation, shaped by forces, tamed by scales. The mathematics remained firm, but the stories behind each equation made them human: promises kept (continuity), negotiations (momentum), grudging cooperation (viscosity), and the stubborn small regions that decide outcomes (boundary layers).

Why "Foundation of Fluid Mechanics" by S.W. Yuan is Essential
Yuan’s textbook is celebrated for its highly organized, logical progression. It moves from fundamental physics to highly complex, compressible, and viscous flow regimes. 1. Kinematics and Dynamics of Fluid Flow Yuan's Foundations of Fluid Mechanics is currently out
A major highlight of the text is its uncompromised derivation of the fundamental conservation laws: The Continuity Equation. Conservation of Momentum: The Navier-Stokes Equations.
: Focuses on conservation laws, including the conservation of mass (continuity equation), momentum, and energy. Fluid Properties & Statics The mathematics remained firm, but the stories behind
Kinematics focuses on the geometry of motion without considering the forces causing that motion.
It teaches students how to solve problems using calculus and differential equations, rather than just plugging numbers into code.
