Pressure in Liquid and Gases Learning Objective and Success Criteria LO: - Explain how a hydraulic system works Progress Step 1: Progress Step 3: describe how pressure is Progress Step 2: Explain how a hydraulic caused in liquids and press works gases Explain why liquids are used in hydraulic systems Solids, liquids and gases Pressure in a gas Liquids cannot be compressed because the particles are already close together This means that liquids can be used to send forces from one place to another in hydraulic systems Liquids cannot be compressed because the particles are already close together Hydraulic systems Y X Brake system Hydraulic systems Force = 20N Force = 10N Piston X puts pressure on the Y liquid X Area = 10cm2 Area = 40cm2 How do we calculate the pressure that is being applied from piston X? Hydraulic systems Force = 20N Force = 10N f X Y p a Area = 10cm2 pressure = force Area = 40cm2 area Hydraulic systems Force = 20N Force = 10N The pressure stays the same throughout the Y X liquid Area = 10cm2 The same as piston X = 1N/cm2 Area = 40cm2 What would the pressure be at piston Y?
