Unit 1
Fluid Mechanics • Fluid : substance can able to flow under the action of shear force • Mechanics: The oldest physical science that deals with both stationary and moving bodies under the influence of forces. • Statics: The branch of mechanics that deals with bodies at rest. • Dynamics: The branch that deals with bodies in motion. • Fluid mechanics: The science that deals with the behavior of fluids at rest (fluid statics) or in motion (fluid dynamics), and the interaction of fluids with solids or other fluids at the boundaries.
