Applied Fluid Mechanics: Principles, Applications, and Practice Text Examples

This course covers the basics, working equations, and applications of fluid mechanics. It has extensive impacts on various fields such as chemical manufacture, automotive systems, and more. Through a mathematical and empirical approach, students learn to describe systems, make assumptions, solve problems, and present results logically. Active learning styles include working problems, applying knowledge in labs, and discussing concepts in class. The emphasis is on understanding principles, working equations, and solving problems systematically. The course content includes properties of fluids, pressures, unit systems, and practical examples. By following a structured and organized approach, students can achieve reasonable and meaningful results in fluid mechanics applications in real-world scenarios.

Presentation Transcript

  1. Fluid Mechanics Principles & Applications • Facultyweb.kennesaw.edu • KSU e-mail • “afm” • Syllabus • Notes - schedules • Power Point

  2. AFM • Outcomes • Credits • Text: Applied Fluid Mechanics, 6th Edition, Robert Mott

  3. AFM • Impacts: chemical manufacture, automobile systems, electrical generation, petroleum refining, water treatment

  4. AFM • Extensive impact on everyday life • Home hot water system • Potable water • Waste water • Natural gas • HVAC • Refrigeration

  5. AFM • Automobiles: fuel system, cooling system, brakes, power steering • Manufacturing: machine operations • Farming: harvesting • Construction: earth moving • Mining • Aircraft: control surfaces, landing gear

  6. AFM • Mathematical approach → empirical approach • AFM: basics → working equation → application

  7. Practice Text examples, class examples, homework, tests

  8. AFM • Learn A • A basis for learning B • Read text • Examples • Homework • Questions • One minute paper

  9. AFM • Learning Styles: Improves understanding and retention. • Active – work problems, apply in lab, discuss in class, explain to someone. • Visual – pictures, diagrams, demonstrations. • Sequential – build knowledge in logical steps

  10. AFM • “You can take this course one of two ways, seriously or again.” Dr. Neathery – Oklahoma State Univ.

  11. AFM • Technicians: trained in set procedures; focus on how, what, when. • Engineers: learned basics; know why. Broader knowledge base.

  12. AFM • No cookbook • Orderly/logical approach • Read carefully • Describe system • Sketch • Assumptions • Principles & working equations; tables & graphs • Solve • Reasonable

  13. Approach • “Most difficulties encountered are due not to lack of knowledge, rather due to lack of organization (of what you know).” Dr. Cengel, N.C. State Univ.

  14. AFM • Assumptions – reasonable

  15. Solve Equation • Include units • Consistent unit system • Significant digits • Equation is a representation of an actual physical process, not an exercise in mathematics.

  16. AFM • Reasonable result • Make sense? • Sign • Units • Magnitude

  17. AFM • Presentations in real world: bosses & customers: logical, neat, & orderly • In AFM, to Instructor. Use same standard

  18. AFM • Solid mechanics – objects stationary (statics) or moving (dynamics) • Fluid mechanics – fluids at rest or in motion • Gas – fills available volume; no resistance to stress • Liquid – limited volume; responds to stress by continuous deformation.

  19. AFM • Gases – compressible • Liquids – ordinarily incompressible. • Hydrostatics • Hydrodynamics: closed pipe, open channel, external flow

  20. Unit Systems • SI • USCS

  21. Properties • Characteristics of system • Mass • Weight • Density • Specific weight • Specific gravity

  22. Properties • Specific volume • Ideal gas law • Compressibility: bulk modulus • Temperature • Engineering • Absolute

  23. Viscosity • Resistance to deformation • Proportionality constant • Absolute • Kinematic

  24. Viscosity • Temperature dependence • Liquid • Gas • Shear dependence - rheology

  25. Pressure • Intensity of a force • System property • Vs reference: gage, atmospheric, absolute • Pascal’s Paradox • Manometer • Barometer • U-tube

  26. Examples • Mercury manometer is connected to an air duct to measure its insice pressure. The manometer deflection is 15mm. Atmospheric pressure is 100kPa. Find the duct’s absolute pressure. Hg  = 13,600kg/m3.

  27. Examples • Refer figure. Find the manometer deflection.

  28. Pascal’s Law • An increase in pressure in an enclosed system will be transmitted throughout the entire system.

  29. Hydraulic jack: Homework • Exert 100N on jack handle; support what force?

  30. Homework • Oil with a specific gravity 0f 0.8 forms a layer 0.9m deep in an open tank that is otherwise filled with water having a depth of 2.10m. The water temperature is 10oC. • Calculate h • Calculate P at the bottom of the tank in gage pressure

  31. Assignment • Mott: Chapters 1, 2, & 3

  32. QUESTIONS

  33. References • Images & examples • Fluid Mechanics Fundamentals & Applications, 6th Edition, Cengel & Cimbala, McGraw Hill • Applied Fluid Mechanics, 6th Edition, Mott, Prentice Hall • Engineering Fluid Mechanics, 5th Edition Crowe, Elger, & Roberson, Wiley • Which of the problems were helpful? • Why?
