Pascal's Principle Lesson

Pascal states that

• Pressure is force per unit area

• When velocity is higher, the pressure is lower

• When force is applied, the pressure is transmitted equally through the fluid

• Pressure transmitted is directly proportional to the force applied

Which object involving pascal principle

• 
• 
• 
• 

Which comparison is correct

• F1 = F2

• P1 > P2

• F1 > F2

• P1 = P2

Weight of the car is 2.6 x 10⁶ kg. Ratio between master piston to slave piston is 1 : 15. What if force exerted to the master piston.

• 1.3 x 10⁶ N

• 1.3 x 10⁷ N

• 3.0 x 10⁶ N

• 3.0 x 10⁷ N

Why oil is the best fluid used in hydraulic system

• Oil low density

• Oil is incompressible

• Oil low specific heat capacity

• Oil is opaque

If a force 20N is applied to piston C. What is the pressure exerted to piston A

• 4.0 x 10² Pa

• 4.0 x 10⁴ Pa

• 2.0 x 10² Pa

• 2.0 x 10⁴ Pa

Which statement is correct

• P _{a =} P _{b =} P _c

• A _{a =} A _{b =} A _c

• F _{a =} F _{b =} F _c

What does a hydraulic system do?

• decreases surface area

• increases velocity

• multiplies force

• decreases pressure

This principle says that an increase in pressure on a confined fluid is transmitted equally to all parts of the fluid.

• Newton's Principle

• Bernoulli's Principle

• Archimedes' Principle

• Pascal's Principle
