Presentation Transcript

  1. Reports • Lab Reports for first lab session are due.

  2. Reports • FORMAT • Exactly • Procedure • Data section • Curves • Conclusions • Significant figures

  3. Housekeeping • Return equipment to proper storage after use. • Clean up spills and litter.

  4. Fluid Statics Forces on submerged surfaces considered by design engineer Retaining walls Dams Tanks Weirs

  5. Fluid Statics • Forces acting on surfaces restraining liquid. • Normal force acting on surface • Horizontal • Vertical

  6. Fluid statics • Liquid at rest: F = 0 • Horizontal: equal in all directions • Vertical: dependent on depth • F = (PA)2+ W - (PA)1 • W = Ah • P = h

  7. Fluid Statics •  constant for incompressible fluid • Pressure prism • Resultant force • Direction • Magnitude • Point of application

  8. Fluid statics • F = YcA • Ycp = Yc + (Ic/ YcA)

  9. Lab • M = 0 • (h + H) Fs = D Fw • Vs P = h

  10. Buoyancy • Archimedes • Fb = FVo • Compare volume calculated from buoyancy vs measured volume.
