Syllabus for EGM-331

Fluid Mechanics is defined as the science that deals with the behavior of fluids at rest (fluid statics) and 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, result in lift and drag forces. Analysis of the velocity boundary layer formed when there is parallel flow over a 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.

Thomas Edison State College is committed to maintaining academic quality, excellence, and honesty. The College expects all members of its community to share the commitment to academic integrity, an essential component of a quality academic experience.

Students at Thomas Edison State College are expected to exhibit the highest level of academic citizenship. In particular, students are expected to read and follow all policies, procedures, and program information guidelines contained in publications; pursue their learning goals with honesty and integrity; demonstrate that they are progressing satisfactorily and in a timely fashion by meeting course deadlines and following outlined procedures; observe a code of mutual respect in dealing with mentors, staff, and other students; behave in a manner consistent with the standards and codes of the profession in which they are practicing; keep official records updated regarding changes in name, address, telephone number, or e-mail address; and meet financial obligations in a timely manner. Students not practicing good academic citizenship may be subject to disciplinary action including suspension, dismissal, or financial holds on records.

All members of the College community are responsible for reviewing the Academic Code of Conduct Policy in the College Catalog and online at www.tesc.edu.

Thomas Edison State College expects all of its students to approach their education with academic integrity—the pursuit of scholarly activity free from fraud and deception. All mentors and administrative staff members at the College insist on strict standards of academic honesty in all courses. Academic dishonesty undermines this objective. Academic dishonesty can take the following forms:

- Cheating
- Gaining or providing unauthorized access to examinations or using unauthorized materials during exam administration
- Submitting credentials that are false or altered in any way
- Plagiarizing (including copying and pasting from the Internet without using quotation marks and without acknowledging sources)
- Forgery, fabricating information or citations, or falsifying documents
- Submitting the work of another person in whole or in part as your own (including work obtained through document sharing sites, tutoring schools, term paper companies, or other sources)
- Submitting your own previously used assignments without prior permission from the mentor
- Facilitating acts of dishonesty by others (including making tests, papers, and other course assignments available to other students, either directly or through document sharing sites, tutoring schools, term paper companies, or other sources)
- Tampering with the academic work of other students

Thomas Edison State College is committed to helping students understand the seriousness of plagiarism, which is defined as using the work and ideas of others without proper citation. The College takes a strong stance against plagiarism, and students found to be plagiarizing are subject to discipline under the academic code of conduct policy.

If you copy phrases, sentences, paragraphs, or whole documents word-for-word—or if you paraphrase by changing a word here and there—without identifying the author, or without identifying it as a direct quote, then you are plagiarizing. Please keep in mind that this type of identification applies to Internet sources as well as to print-based sources. Copying and pasting from the Internet, without using quotation marks and without acknowledging sources, constitutes plagiarism. (For information about how to cite Internet sources, see Online Student Handbook > Academic Standards > “Citing Sources.”)

Accidentally copying the words and ideas of another writer does not excuse the charge of plagiarism. It is easy to jot down notes and ideas from many sources and then write your own paper without knowing which words are your own and which are someone else’s. It is more difficult to keep track of each and every source. However, the conscientious writer who wishes to avoid plagiarizing never fails to keep careful track of sources.

Always be aware that if you write without acknowledging the sources of your ideas, you run the risk of being charged with plagiarism.

Clearly, plagiarism, no matter the degree of intent to deceive, defeats the purpose of education. If you plagiarize deliberately, you are not educating yourself, and you are wasting your time on courses meant to improve your skills. If you plagiarize through carelessness, you are deceiving yourself.

Acts of both intentional and unintentional plagiarism violate the Academic Code of Conduct.

If an incident of plagiarism is an isolated minor oversight or an obvious result of ignorance of proper citation requirements, the mentor may handle the matter as a learning exercise. Appropriate consequences may include the completion of tutorials, assignment rewrites, or any other reasonable learning tool in addition to a lower grade for the assignment or course. The mentor will notify the student and appropriate dean of the consequence by e-mail.

If the plagiarism appears intentional and/or is more than an isolated incident, the mentor will refer the matter to the appropriate dean, who will gather information about the violation(s) from the mentor and student, as necessary. The dean will review the matter and notify the student in writing of the specifics of the charge and the sanction to be imposed.

Possible sanctions include:

- Lower or failing grade for an assignment
- Lower or failing grade for the course
- Rescinding credits
- Rescinding certificates or degrees
- Recording academic sanctions on the transcript
- Suspension from the College
- Dismissal from the College
