Engineering Fluid Mechanics 5 Information and Introduction

Course Description
This course is an introduction to fluid mechanics, and emphasizes fundamental concepts and problem-solving techniques. Topics to be covered include:
Fluid properties. Fluid statics. Fluid kinematics. Control volume analysis. Internal flows (pipe flows). External flows (lift and drag). Turbomachinery (pumps and turbines).

Students are expected:

To read the assigned portions of the text! To be proficient in applying:
Mathematics (e.g., integration, differentiation, and differential equations) Statics and dynamics (e.g., free body diagrams) Thermodynamics (e.g., the first law)

Course Objectives (I)

Upon completion of this course, students should be able to:
1. Articulate the properties that distinguish fluids from other forms of matter, and the broad range of engineering applications which involve fluid mechanics. 2. Apply the concepts of vector fields (velocity, force acceleration), scalar fields (pressure, density, temperature), and vector differential and integral calculus to engineering analysis of fluids systems, and to the interpretation of flow physics through the conservation laws. 3. Properly apply Newton's second law to analysis and design involving fluids at rest using integral and differential calculus, including pressure variation, forces and moments on plane surfaces, and buoyancy. 4. Properly apply systems and control volume methods based on mass, momentum, and energy conservation, as appropriate, to the analysis and design of engineering fluids systems. 5. Properly apply mass, momentum, and energy conservation to steady internal (pipe) flows, correctly interpret and apply laminar and turbulent flow models, and estimate head loss and power requirements in piping systems.

Homework
Philosophy:
One of the best ways to learn something is through practice and repetition. Therefore, homework assignments are extremely important in this class! Homework sets will be carefully designed, challenging, and comprehensive. If you study and understand the homework, you should not have to struggle with the exams.

Information and Introduction

Homework
Policy:
Homework turned will receive credit according to the following rules:
1. 100% if turned in the due date. 2. No credit if turned in after due date.

Exceptions will be made only under extreme circumstances. Solutions will be made available within a week after the due date. To ease grading, homework submissions MUST follow specified format.
Engineering Fluid Mechanics 14 Information and Introduction

Homework
Policy, continued:
Students are allowed (and encouraged) to work in groups of three on the homework assignments, provided that each person in the group is contributing to each solution. Only one completed assignment needs to be turned in per group. Please make sure that each student's name is indicated clearly on the cover page of the homework assignment. All students in a group will receive the same grade for that assignment Only a subset of assigned problems will be thoroughly graded. The remaining problems will only be checked for correct answers
