This Fluid Mechanics course, designed for second-year Mechanical Engineering students at University of BLIDA 1, covers essential concepts aligned with the Bachelor's curriculum. It is divided into four chapters: the first focuses on fluid properties like density, viscosity, and surface tension; the second covers fluid statics, including pressure and buoyancy; the third discusses ideal fluid dynamics, introducing Bernoulli's equation; and the fourth addresses real fluid dynamics, incorporating viscosity effects and practical applications. By the end of the course, students will be equipped with the theoretical and practical tools to solve fluid-related engineering problems in various fields.
