Pressure in a Column of Liquid

• What 2 factors affect the pressure in a column of liquid?

  The height of the column and the density of the liquid
• The higher the column above the point, and the more dense the liquid : the greater the weight above the point - the greater the force on the surface at that point - the greater the pressure
• What is the equation for pressure in a column of liquid?

  Pressure = height (of column) x density (of liquid) x gravitational field strength
• Pressure is measured in pascals (Pa)
• Height of column is measured in metres (m)
• Density is measured in kilograms per metre cubed (k/gm³)
