Question

State the principle of transmission of pressure in fluids. ( Pascal's Principle) ​

Answer 1

Answer:

Pascal's principle, an experimentally verified fact, is what makes pressure so important in fluids. ... Since a change in pressure is transmitted undiminished in an enclosed fluid, we often know more about pressure than other physical quantities in fluids.

hope it is helpful for you happy Diwali on this i wish your all wishes may comes true stay safe stay home

Answer 2

Pascal's principle, often known as Pascal's law, is a statement in fluid (gas or liquid) mechanics that a pressure change in one component of a fluid at rest in a closed container is transferred without loss to all other parts of the fluid and to the container walls.

• Pascal Law is also known as the Principle of Transmission of Pressure in Fluids.
• Blaise Pascal, a French scientist, was the first to state the principle.
• The force divided by the area on which it operates equals the pressure.
• A pressure applied on one piston in a hydraulic system causes an equivalent increase in pressure on another piston in the system, as per Pascal's principle.
• When the area of the second piston is ten times that of the first, the force on the second piston is ten times more, even though the pressure is the same.
• The hydraulic press, which is based on Pascal's concept and used in hydraulic brakes, is an example of this effect.
• Pascal also established that the pressure at a resting point in a fluid is the same in all directions.
