1

• AP Physics Chapter 10 Fluids Exam Review
• What is pressure? What is the SI unit of
  pressure?
• the perpendicular force per unit area or p
  F-/A Pascal (Pa)
• What is gauge pressure?
• the difference between the pressure you are
  measuring and atmospheric pressure
• 3) What is density? What is the density of water?
• the mass per unit volume or ? m/V 1000 kg/m3
• 4) Why does pressure increase as you dive into
  deeper water?
• the weight of the water above your head
  increases the pressure
• 5) What is the pressure-depth equation?
• P Po ?gh
• 6) What is Pascals principle? What is a real
  world application of this principle?
• pressure applied to an enclosed fluid is
  transmitted to every point in the fluid and the
  enclosure walls, or

2

• 7) What is Archimedes Principle?
• the buoyant force is equal to the weight of the
  displaced fluid, or
• Fb Wf mfg ?gVf
• Only count the volume of the object that is
  submerged.
• 8) What is the continuity equation (flow rate
  equation)?
• The flow rate through a vessel is constant.
  Where the vessel is the most narrow, the velocity
  is the greatest, or A1v1 A2V2
• 9) What is Bernoullis Equation?
• P1 ½ ?v12 ?gy1 P2 ½ ?v22 ?gy2
  constant
• 10) What is the velocity of water through a hold
  in a container a distance h below the surface?
• v v2gh Add this equation to your gold
  equation sheet
• 11) According to Bernoullis Equation, where is
  the pressure high at a place in the vessel where
  the flow rate is high or low?
• low
• 12) What is a real world application of
  Bernoullis equation?
• calculating lift on an airplane calculating
  velocity of liquid out of a container
