Transmitting Pressure in a Fluid

Force, Pressure and Area.  The force acting on a certain area is called pressure  If you change the area but keep the force the same the pressure changes.

General idea:  The column of air exerts a force on the surface of the earth.  This force per area is as large as 1.03x10 5 Pa at sea level, also known.

Chapter 11 Fluids

Any change in the pressure applied 11.5 Pascal’s Principle PASCAL’S PRINCIPLE Any change in the pressure applied to a completely enclosed fluid is transmitted undiminished to all parts of the fluid and enclosing walls.

11.5 Pascal’s Principle

The input piston has a radius of 0.0120 m 11.5 Pascal’s Principle Example 7 A Car Lift The input piston has a radius of 0.0120 m and the output plunger has a radius of 0.150 m. The combined weight of the car and the plunger is 20500 N. Suppose that the input piston has a negligible weight and the bottom surfaces of the piston and plunger are at the same level. What is the required input force?
