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

6. AFM Automobiles: fuel system, cooling system, brakes, power steering
Manufacturing: machine operations
Farming: harvesting
Construction: earth moving

Aircraft: control surfaces, landing gear

7. AFM Mathematical approach → empirical approach
AFM: basics → working equation → application

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

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

10. 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

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

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

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

14. 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.

15. AFM
Assumptions – reasonable

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

17. AFM

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

19. 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.

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

22. Unit Systems SI
USCS

23. Properties Characteristics of system Mass Weight Density
Specific weight
Specific gravity

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

25. Viscosity Resistance to deformation Proportionality constant Absolute
Kinematic

26. Viscosity Temperature dependence Liquid Gas
Shear dependence - rheology

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

34. 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.

36. Examples
Refer figure. Find the manometer deflection.

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

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

43. 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

44. Assignment
Mott: Chapters 1, 2, & 3
