Syllabus for EGM-331
FLUID MECHANICS
This course covers fundamental fluid statics, including manometer, forces on submerged surfaces, and Archimedes’ principle. Details of the course include one-dimensional incompressible flow; conservation laws and application to flowing systems, cavitation, impulse-momentum problems, vanes; and pipe flows, laminar analyses, turbulent flows with emphasis on calculation of fluid properties. Other topics include one-dimensional compressible flow; conservation laws; specialization to isentropic situation; and nature of speed of sound. Applications including effects of area change, converging and diverging nozzles, choking phenomena’s, and normal shock waves.
Fluid Mechanics is defined as the science that deals with the behavior of fluids at rest (fluid statics), fluids in motion (fluid dynamics), and the interaction of fluids with solids or other fluids at the boundaries.
Recall that stress is defined as force per unit area. The normal (perpendicular) component of a force acting on a surface per unit area is called the normal stress and for a fluid at rest, is known as pressure. The tangential (parallel) component of a force acting on a surface per unit area is called shear stress. A fluid at rest is at a state of zero shear stress.
To begin, we must first understand what is called the no-slip condition between some fluid and a solid surface (which is the development of boundary layers between the two). Next, we classify various types of fluid flow (viscous versus inviscid regions of flow, internal versus external flow, compressible versus incompressible flow, laminar versus turbulent flow, natural versus forced flow, and steady versus unsteady flow). Fluid properties, such as vapor pressure and viscosity, and boundary properties, such as surface tension, are discussed and used to describe various fluid flow problems encountered in practice.
In studying fluid statics, hydrostatic forces acting on submerged bodies are considered. The buoyant force applied by fluids on submerged or floating bodies and the stability of such bodies are examined.
Bernoulli’s equation is derived by applying Newton’s second law to a fluid element along a streamline. The conservation of kinetic, potential, and flow energies of a fluid, where viscous forces are negligible, results in an energy equation that is used in a variety of applications.
To solve fluid flow problems fast and simply, without a significant loss of accuracy, a finite control volume momentum analysis is presented. Using Reynolds transport theorem and Newton’s laws, the linear and angular momentum equations for control volumes are developed. These are used to determine the forces and torques associated with fluid flow.
Flow through pipes and ducts, including entrance region and the fully developed region, is analyzed. The pressure drop associated with fluid flows is used to determine pumping power requirements for various piping systems.
External flow, which is flow over bodies that are immersed in a fluid, results in lift and drag forces. Analysis of the velocity boundary layer formed when there is parallel flow over various surfaces provides relations for skin friction and drag coefficients. The lift developed by airfoils and factors that affect the lift characteristics of bodies are discussed.
After completing this course, you should be able to:
CO1 Classify fluid flow in terms of fluid properties, including viscosity, vapor pressure, velocity fields,
surface tension, capillary effect, and cavitation.
CO2 Explain how hydrostatic forces act on submerged plane and curved surfaces and account for
buoyancy and stability effects.
CO3 Use data from manometers such as the piezometer tube, the U-tube, or the pitot-static tube to
measure pressure differences and determine flows.
CO4 Derive Bernoulli’s equation for steady, inviscid, incompressible flow using Newton’s second law
and conservation of energy principle.
CO5 Use Bernoulli’s equation to solve problems involving confined flows, free jets, and flow-rate
measurements (orifice, nozzle, venturi meter).
CO6 State Reynolds transport theorem for flow (steady and unsteady) through a control volume.
CO7 Solve fluid flow problems where the flow is steady or unsteady using the continuity equation and
a fixed, non-deforming control volume.
CO8 Distinguish between laminar flow and turbulent flow in pipes.
CO9 Solve fluid flow problems using different piping networks.
CO10 State the three pump laws for centrifugal pumps and apply them to pump situations.
CO11 Explain the concept of drag and lift for flows over plane, cylindrical, and spherical
surfaces.
CO12 Describe how friction and pressure drag affects fluid flows inside and outside various fixed,
non-deforming geometrical shapes.

If there is evidence that you have cheated or plagiarized in your exam, the exam will be declared invalid, and you will fail the course.
Your grade in the course will be determined as follows:
All activities will receive a numerical grade of 0–100. You will receive a score of 0 for any work not submitted. Your final grade in the course will be a letter grade. Letter grade equivalents for numerical grades are as follows:
A | = | 93–100 | C+ | = | 78–79 | |
A– | = | 90–92 | C | = | 73–77 | |
B+ | = | 88–89 | C– | = | 70–72 | |
B | = | 83–87 | D | = | 60–69 | |
B– | = | 80–82 | F | = | Below 60 |
To receive credit for the course, you must earn a letter grade of C or better (for an area of study course) or D or better (for a course not in your area of study), based on the weighted average of all assigned course work (e.g., exams, assignments, discussion postings).
