Matter and Materials: State, evaluate and apply properties of fluids on everyday life and industrial contexts

• Define and apply hydrostatic pressure and its relation to depth and density of a liquid.
• Define, give examples of, and use Pascal’s principle.
• Describe fluid flow and use a Venturi meter to show the relationship between pressure, cross-section of the pipe changes speed of fluid flow.

By the end of this unit you will be able to:

• Define, describe and calculate hydrostatic pressure in relation to the density and depth of a liquid.
• Use Pascal’s principle and state common uses of this principle.
• Show the relationship between pressure and the speed of fluid flow using a Venturi meter.
