This lesson

•  Worksheet pressure
• Hydraulics exercise

Learning goals

• Be able to calculate pressure, force and area in hydraulic systems.
• Explain how hydraulic systems work in your own words.
• Explain the difference between pressure in gas and pressure in liquids in your own words.

Worksheet pressure

Hydraulics

In a hydraulic jack a force of 20 Newton is applied to a piston with an area of 0.20 m2. The area of the other piston is 2.0 m2. 

 

a) What is the pressure transmitted through the liquid?

b) What is the force applied to the other piston?

Pressure in gasses

Gas and liquid?

What is a gas?

What is the difference between a gas and a liquid?

• Liquids are incompressible 
  
• Gasses are compressible
  

Pressure, volume and temperature
