Course Description : Application of the basic and advance knowledge in fluids statics

and dynamics, which includes mass, momentum, energy

conservation principle.

Course Objectives : 1) To describe the basic fundamental principles of fluid

mechanics such as continuum concept, viscosity, pressure,

hydrostatic force, mass conservation principle, momentum

conservation principle energy conservation, fluid frictions and

boundary layer.

2) To apply the basic principle to derive equations that govern

behaviour of flowing fluid namely the Navier-Stokes Equations
