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

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

7. 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

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

10. Fluid statics F =  Y c A Y cp = Y c + (I c / Y c A)

12. Lab  M = 0 (h + H) F s = D F w Vs P =  h

15. Buoyancy Archimedes F b =  F V o Compare volume calculated from buoyancy vs measured volume.
