4 cards from this section. Quick, good the night before a test.
Define pressure.
Think about how force and area relate.
What unit is pressure measured in?
Recall the relationship between Newtons and area.
What is pressure defined as?
Remember how pressure is calculated.
Pascal's Law applies to which kind of fluids?
Consider the behavior of fluids under pressure.
A diver is at a depth of 30 meters in the ocean. Calculate the pressure experienced by the diver. Use the density of seawater as 1025 kg/m³ and g = 9.81 m/s². Include atmospheric pressure.
Remember to account for atmospheric pressure.
A hydraulic press has a small piston with an area of 0.01 m² and a larger piston with an area of 0.10 m². If a force of 100 N is applied to the small piston, calculate the force exerted by the large piston.
Use Pascal's Law to find the relationship between forces and areas.
