2 cards from this section. Quick, good the night before a test.
What is Pascal's Law?
Think about how pressure behaves in liquids.
Explain what gauge pressure is.
It’s what many pressure measurements refer to.
What does Pascal's Law state?
Think about how pressure behaves in a hydraulic lift.
True or False: Gauge pressure includes atmospheric pressure.
Remember the basics of gauge pressure.
A hydraulic press has a small diameter piston of 0.5 cm and a larger diameter piston of 5 cm. If 200 N of force is applied to the small piston, what force can be lifted at the larger piston?
Use the area ratio to find the force based on Pascal's principles.
Calculate the pressure 15 meters deep in a lake, given the temperature is 20°C and the density of water is 1000 kg/m³.
Don't forget to include atmospheric pressure in your calculation!
