Sample Problem 1:
What is the direction of shear stress inside a fluid and on the walls?
- Sample Problem 2: Through a very narrow gap of height h a thin plate of very large extent is being pulled at constant velocity V. On one side of the plate is oil of viscosity m and on the other side oil of viscosity km. Calculate the position of the plate so that the drag force on it will be a minimum.
- Sample Problem 3: How can a pine needle stay on a water surface without sinking?
