Pressure in Fluids

• Fluid


  Collective term for gases and liquids
• When we are inside any fluid we feel the pressure
• Pressure in fluids always acts in all directions
• Density


  Mass per unit volume
• Density of water


  • 1000 kg/m3 = 1000 kgm-3
• Each cubic metre of water will have a mass of 1 000kg
• Pressure in any fluid depends on

  • Depth in the fluid (h)
  • Density of the fluid (ρ) =rho
  • Acceleration due to gravity (g)
• Formula for pressure in fluids
