## Level 2: Fluid Mechanics

Reference
PE

Objectives

Introduce the basic concepts of fluid mechanics including fluid properties, hydrostatics and fluids in motion.

Cover the applications of these concepts to allow students to calculate pressure distributions in static fluids, forces on immersed surfaces and pressure losses for steady incompressible flows in piping systems. The course also introduces the instrumentation used to measure pressure, flow velocity and flow rates.

In order to impart problem-solving skills, a large number of applied problems is treated in class and as homework.
