1. Fluid Properties Solid-Liquid-Gas Solid under shear vs Liquid under Shear Viscosity Newtonian vs. Non-Newtonian Compressible vs. Non-Compressible Specific Weight Surface Tension Vapor Pressure

2. Solid-Liquid and Gas

3. Top layer of fluid moves with velocity of block Imagine an elastic solid held between two Plates-and then applying a shear force To the top plate Then imagine a long open tank (flume) holding water with a wood block floating on the surface And then apply a shear force to the wood Bottom layer does not move—The NO SLIP condition

5. Contrast to solid u displacement shear modulus Strain-deformation

8. ly

14. Why 2

16. Note dependence on R Recall  g is  specific weight

18. Boiling will occur In Denver the atmospheric pressure is only 95% (see page 40) On Everest only 75%--the boiling points are reduced accordingly
