pressure in fluids

• Fluid


  Gases and liquids
• Calculating pressure of a fluid acting on a surface

  Force of fluid normal to surface / Area of surface
• Pressure is measured in Pascals
• Pressure = Force / Area
• Atmosphere


  • Thin layer of air on Earth
  • Most dense at Earth's surface
  • Decreases in density as altitude increases
• Increase in altitude


  Decrease in atmospheric pressure
