Pressure

• Pressure

  • Concentration of force per unit of area
  • Measured in pascals or kilopascals (Pa / kPa)

  P = F/A P = Pressure (Pa or kPa)

  F = Force (N)

  A = Area (M²)

  A) Force (N)

  B) Area (M²)

  C) Pressure (Pa / kPa)

  
• Pressure in Fluids (Liquids & Gasses)

  • Pressure is excerted equally in all directions
  • Pressure increases with depth

  P = hρg P = Pressure difference (Pa/kPa)

  h = Height (m/cm)

  ρ = Density (kg/m³)

  g = gravitational field strength (N/Kg)

  • Pressure increases with depth. This is because particles at the bottom of a container are pushed on by the weight of the particles further up, which causes it to be under higher pressure

  A) PD (Pa/kPa)

  B) Height (m/cm)

  C) Density (Kg/m³, Kg/cm³

  D) GFS (10)
