This was studied byBLAISE PASCAL

Blaise Pascal• was

a French mathematician,  physicist, inventor, writer and Catholic philosopher.

• Pascal's earliest work was in the natural and applied sciences where he made important contributions to the study of fluids, and clarified the concepts of pressure and vacuum by generalizing the work of Evangelista Torricelli.

PASCAL PRINCIPLE

• "pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains same."

Page 5: Pascal's Principles - ppt

“Example”

Page 6: Pascal's Principles - ppt

• If the whole pressure is increased on the whole surface of the liquid at rest, the pressure in any point in the liquid increases by the same amount.

• Pressure applied to an enclosed fluid is transmitted undiminished to every point in the fluid and the sides of the container.

We can measure the amount of pressure happen during the PROCESS of the

principle examples

• Thus, Pi = Po so..

• Fi (input force) = Fo (output force)

Ai (input area) Ao (output area)

To get the Area> A= πd2

Example problem

• A garage lift has a pistons of diameters 10 cm and 40 cm, respectively. It is used to lift a car with a weight of 1.8 x 104 N.

• Find the input force..

Page 11: Pascal's Principles - ppt

Given:

• D1= 10 cm

• D2= 40 cm

• Fo= 1.8 x 104 N

• Fi= ???

Page 12: Pascal's Principles - ppt

sOlution

• If Fi is missing, you need to derived from the real formula to find Fi

• Fi = FO AiAo

Page 13: Pascal's Principles - ppt

• Fi= Fo Ai Ao

= (1.8 x 104) (π10 cm2/4)π40 cm2/4

= (1.8 x 104) (π10 cm2/4) π40 cm2/4

= (1.8 x 104) 78.51,256

= 1,125 N = 1.13 x 103 N
