CONTENT: "Laminar and turbulent flow of ideal and viscous fluids, pipe flow, boundary layers, wing theory, supersonic flow, nozzles, shock waves." Per WSU 2000-2001 course catalog. NOTE: beginning in Fall 2000, material on supersonic flow, nozzles, and shock waves will no longer be formally covered to allow expanded coverage of the remaining material. See course schedule below, as well as ME 303 Syllabus for futher details.

PREREQUISITES: Physics 202 and major in Engineering. Previous completion of, or concurrent enrollment in ME 301 (Thermodynamics) is recommended but not required. Prerequisites by topic:

Differentiation and integration.
Simple vector operations.
Concepts of velocity, acceleration, force and energy.
Newton’s laws of motion.
Basic thermodynamic concepts such as systems and properties.
Resolution of forces and moments from free body diagrams in statics and dynamics.

OBJECTIVES: The course provides an introduction to fundamental practical and theoretical principles governing the behavior of static and flowing fluids. Through homework, quizzes, and the final exam, students demonstrate competence in topics on fluid flow such as are encountered on the Fundamentals of Engineering (E.I.T.) and Professional Engineer's (PE) License exams. Students become familiar with relevant professional references, and with application of computers to analysis and design related to fluid flow and fluid systems. The course provides the necessary background for study of Heat Transfer (ME 404) and other courses requiring a fundamental understanding of fluid behavior. Specific topics for study include...

Understanding the properties of fluids
Calculating forces on a submerged structure in a static fluid.
Applying the mass conservation principle, using the control volume approach, to engineering problems
Using Euler’s and Bernoulli’s equations to calculate pressure variations in accelerating fluids.
Applying the momentum and energy equations to engineering problems.
Using dimensional analysis for scaling and data reduction.
Calculating surface resistance in laminar and turbulent flows.
Evaluating head loss in pipes and conduits.
Calculating lift and drag on moving bodies.

STUDENT OUTCOMES: Students will be expected to develop the following skills/understandings upon successful completion of the course.

Ability to solve manometer problems, and calculate forces on submerged and floating bodies.
Ability to use conservation of mass principle to calculate flow rates through control volumes.
Ability to calculate accelerations and associated pressure variations in moving fluids using Euler’s and Bernoulli’s equations.
Ability to analyze momentum fluxes through a control volume and hence calculate forces in moving fluids.
Ability to apply conservation laws for mass, momentum and mechanical energy in combination to control volumes in ideal fluids and hence calculate hydraulic and energy grade lines.
Ability to calculate local and overall skin friction drag in laminar and turbulent flat plate boundary layers, using approximate empirical formula.
Ability to solve hydraulic pipe flow problems using Moody’s diagram for skin friction to calculate flow rate/ pressure loss / pipe diameter.
Ability to use dimensional analysis and similarity considerations in the design and interpretation of scale model experiments.
Ability to calculate lift and drag forces for simple aerodynamic shapes like airfoils, cylinders and spheres using published charts of aerodynamic coefficients.

COMPUTER USE: Computer use is required for selected assignments. Access to the course WEB site is required.

TEXTBOOK: Engineering Fluid Mechanics, by Roberson & Crowe, 6th edition, Wiley. New and used copies are available from Students' Book Corporation; call (509)375-1084 (WSU-TC Bookie) to mailorder.
