Fluid Mechanics presents the behavior of liquids and gases at rest and in motion. This practical textbook develops the subject from basic properties and pressure measurement through continuity, Bernoulli’s equation, pipe flow, open-channel flow, boundary layers, dimensional analysis, pumps, turbines, and cavitation. Each chapter combines theory, formulas, worked numerical examples, engineering interpretation, and practical applications.
The book is designed for engineering students, diploma learners, technicians, competitive-exam learners, and working professionals who want a structured revision resource. Symbols are introduced before use, assumptions are stated where useful, and calculation methods emphasize units and physical meaning.
