1
Bernoulli’s, Pascal’s, & Archimedes’ Principles Principles of Fluids

2
Bernoulli’s Principle As the Velocity (speed) of a fluid increases, the Pressure exerted by the fluid decreases Why?

3
Bernoulli’s Example

4
Buoyant Force The upward force of a Fluid exerted on an object. What is the downward Force exerted on an object? Gravity

5
Archimedes’ Principle The buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object

6
Archimedes (Example #1) Mass = 20g Volume = 20ml Mass of Fluid= 20g

7
Archimedes (Example #1) Gravity = 20 Buoyant Force = 20 Object is in Liquid

8
Archimedes’ (Example #2) Mass = 50g Volume = 20ml Mass of Fluid= 20g

9
Archimedes (Example #2) Gravity = 50 Buoyant Force = 20 Object SINKS

10
Archimedes’ (Example #3) Mass = 30g Volume = 60ml Mass of Fluid= 60g

11
Archimedes (Example #3) Gravity = 30 Buoyant Force = 60 Object Floats

12
Pascal’s Principle Pressure applied to one place of a fluid is transmitted unchanged throughout the fluid.

13
Pascal’s Principle Liquid What is pressure? What type of fluid works best for this principle? Explain your answer. P = Area Force

14
Pascal’s example AB Area of A = 8 cm 2 Area of B = 50 cm 2 Force = 10,000 N Force ?

15
Break down the problem: AB P = Area Force 1 st solve for P in B P = 50 cm 2 10,000 N P = 200 N cm 2

16
Break down the problem: AB 2 nd solve for F on A P = Area Force F =P x A F = 200 N cm 2 x 8 cm 2 F =1600 N
