575.601.81 - Fluid Mechanics

Expanded Course Description

The practice of chemical, civil, environmental, and mechanical engineering, involves applications of the science of fluid mechanics. This course is intended for those engineers and scientists who may be called upon to analyze, investigate, document, or review issues related to fluid properties and parameters associated with fluid dynamics. This course will also prepare the student to take advanced courses in hydrology and other environmental sciences and engineering areas. Students of this course will be able to apply fundamental relationships of fluid mechanics to analyze fluid systems and flow processes. Students are not expected to have formal training in fluid dynamics; however, they are expected to have exposure to the properties of substances through fundamental college-level undergraduate courses in chemistry, physics, and mathematics through calculus. Some background material, e.g., vectors and tensors, will be reviewed or developed as needed.

Prerequisites 

• College level Physics, Chemistry and Calculus or equivalent.  
• JHU Online Orientation Course (if you have not previously taken a JHU online course).  

Course Structure

The course materials are divided into modules which can be accessed by clicking Modules on the course menu. Each module contains the sections Content and Assignments.  You are encouraged to preview all sections of the module before starting. Most modules run for a period of seven (7) days, exceptions are noted in the Course Outline. You should regularly check the course and assignments Discussions forums, Calendar and Announcements for assignment due dates.

Course Topics

• Fluid definitions, properties, thermodynamics of liquid-gas phase change 
• Pressure under static conditions and forces due to static pressure
• Forces on submerged surfaces and buoyancy
• Integral equations of fluid dynamics (Reynolds Transport Equations)
• Continuity and Bernoulli's Equations
• General Energy Equation
• Laminar and turbulent flow
• Energy loss - friction and minor losses
• Internal flow - sizing piping and pumps
• Open channel flow and hydraulic jump
• Forces due to fluid motion - momentum equation
• Drag and lift due to fluid motion
• Flow of compressible gasses
• Differential Equations of Fluid dynamics (Navier-Stokes Equations)

Course Goals

This course aims to introduce the subject of fluid mechanics and present the system and control volume approaches for analyzing the fluid behavior of internal and external flows. This course will also help students understand fluid properties, liquid-gas phase change phenomena, hydrostatic laws, buoyancy principles, and applying mass, energy, and momentum conservation to fluid systems.

Course Learning Outcomes (CLOs)

• Determine values of fluid properties and relationships between them.
• Apply the principles of mass, momentum, and energy conservation written in form of mathematical equations.
• Analyze practical fluid mechanics problems using the systematic engineering method.
• Evaluate options in selecting design and operational parameters for fluid systems under safety and environmental constraints.

Academic Policies

Deadlines for Adding, Dropping and Withdrawing from Courses

Students may add a course up to one week after the start of the term for that particular course. Students may drop courses according to the drop deadlines outlined in the EP academic calendar (https://ep.jhu.edu/student-services/academic-calendar/). Between the 6th week of the class and prior to the final withdrawal deadline, a student may withdraw from a course with a W on their academic record. A record of the course will remain on the academic record with a W appearing in the grade column to indicate that the student registered and withdrew from the course.

Academic Misconduct Policy

All students are required to read, know, and comply with the Johns Hopkins University Krieger School of Arts and Sciences (KSAS) / Whiting School of Engineering (WSE) Procedures for Handling Allegations of Misconduct by Full-Time and Part-Time Graduate Students.

This policy prohibits academic misconduct, including but not limited to the following: cheating or facilitating cheating; plagiarism; reuse of assignments; unauthorized collaboration; alteration of graded assignments; and unfair competition. Course materials (old assignments, texts, or examinations, etc.) should not be shared unless authorized by the course instructor. Any questions related to this policy should be directed to EP’s academic integrity officer at ep-academic-integrity@jhu.edu.

Students with Disabilities - Accommodations and Accessibility

Johns Hopkins University values diversity and inclusion. We are committed to providing welcoming, equitable, and accessible educational experiences for all students. Students with disabilities (including those with psychological conditions, medical conditions and temporary disabilities) can request accommodations for this course by providing an Accommodation Letter issued by Student Disability Services (SDS). Please request accommodations for this course as early as possible to provide time for effective communication and arrangements.

For further information or to start the process of requesting accommodations, please contact Student Disability Services at Engineering for Professionals, ep-disability-svcs@jhu.edu.

Student Conduct Code

The fundamental purpose of the JHU regulation of student conduct is to promote and to protect the health, safety, welfare, property, and rights of all members of the University community as well as to promote the orderly operation of the University and to safeguard its property and facilities. As members of the University community, students accept certain responsibilities which support the educational mission and create an environment in which all students are afforded the same opportunity to succeed academically.

Classroom Climate

JHU is committed to creating a classroom environment that values the diversity of experiences and perspectives that all students bring. Everyone has the right to be treated with dignity and respect. Fostering an inclusive climate is important. Research and experience show that students who interact with peers who are different from themselves learn new things and experience tangible educational outcomes. At no time in this learning process should someone be singled out or treated unequally on the basis of any seen or unseen part of their identity. 
 
If you have concerns in this course about harassment, discrimination, or any unequal treatment, or if you seek accommodations or resources, please reach out to the course instructor directly. Reporting will never impact your course grade. You may also share concerns with your program chair, the Assistant Dean for Diversity and Inclusion, or the Office of Institutional Equity. In handling reports, people will protect your privacy as much as possible, but faculty and staff are required to officially report information for some cases (e.g. sexual harassment).

Course Auditing

When a student enrolls in an EP course with “audit” status, the student must reach an understanding with the instructor as to what is required to earn the “audit.” If the student does not meet those expectations, the instructor must notify the EP Registration Team [EP-Registration@exchange.johnshopkins.edu] in order for the student to be retroactively dropped or withdrawn from the course (depending on when the "audit" was requested and in accordance with EP registration deadlines). All lecture content will remain accessible to auditing students, but access to all other course material is left to the discretion of the instructor.
