## Fluid Mechanics

**OBJECTIVE**

Provide an introduction to the basic principles of static and dynamic fluids, including fluid properties, pressure and fluid statics, fluid in motion, conservation mass, momentum analysis, dimensional analysis, flow in pipes, differential analysis, Navier-Stokes equation, surface resistance, and boundary layer. This course introduces the application of basic principles of fluid mechanics to solve typical problems of incompressible flow which are of interest in aerospace, civil, mechanical, and petroleum engineering field.

This course is taught entirely in English, with 6 hours per week.
