Pressure & Pressure Differences in Fluids

• What is the Equation for Pressure?

  Pressure =$\frac{Force}{Area}$
• What is the Equation of Pressure in a Liquid?

  $P\ =$$\ h\ \rho\ g$

  • Pressure (P) measured in Pascals (Pa)
  • density ($\rho$) measured in kilograms per metre cubed ($kg/m^3$)
  • height of column (h) measured in metres (m)
  • gravitational field strength (g) measured in newtons per kilogram (N/kg)
• What Does the Pressure Exerted by a Fluid Depend on?

  • Depth
  • Density
