Course Title: Fluid Mechanics I Academic year: 2012/2013

Credit hours: 3 Class Year: II Semester: II

Course Objectives:

The course:

Enables students to understand concepts, principles, laws, observations, and modelsof fluids at rest and in motion,

Provides basis for understanding fluid behavior for engineering design and control offluid systems,

Helps students develop competence with mass, energy and momentum balances fordetermining resultant interactions of flows and engineered and natural systems,

Enables students develop bases for correlating experimental data, designingprocedures, and using scale models of fluid flows,

Enables students to learn the nature of rotation, circulation, resistance (viscous,turbulent), boundary layers, and separation with applications to drag and lift on

objects, and

Enables students learn methods for computing headlosses and flows in simple pipesand channels.

Course Outline:

1. Introduction to fluids: Definition; Properties of fluids; Unit conversion Factors.2. Fluid Statics: Hydrostatics pressure in Fluids; Pressure measurements; Manometers;

Hydrostatics force on different surfaces; Buoyancy; Flotation and stability; Pressure

distribution in rigid body motion.
