2. Newtonian Fluids Gases are considered compressible fluids Liquids are considered incompressible fluids Another thing we pretend is true because the compression is usually a negligible amount Non-Newtonian fluids do not always act predictably

3. Pascal's Principles External pressure applied to a fluid will be applied uniformly throughout the fluid F₁/A₁ = F₂/A₂

4. 50 Newtons is applied to pump a squirt gun with a cylinder surface area of.01 square meters. How much force does it take to plug the barrel of the squirt gun if the area of the opening is 0.001 square meters?

5. Does this obey the law of conservation of energy? Explain your answer!

6. Static Pressure and Depth F=mg and the mass = ρV ρ = density V=area of the cross section x height So F=ρgV= ρgAh p = F/A= ρgh *for a uniform shape

7. Explain this phenomenon:
