Question

describe pascal's law​

Answer 1

Answer:

Pascal's principle, also called Pascal's law, in fluid (gas or liquid) mechanics, statement that, in a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container.

Applications of Pascal's Law

This is the principle of working of hydraulic lift. It works based on the principle of equal pressure transmission throughout a fluid (Pascal's Law). ... Few more applications include a hydraulic jack and hydraulic press and forced amplification is used in the braking system of most cars.

Answer 2

Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.

Force F1 is applied at Piston 1. So generated Pressure in the fluid medium

of the container is, P1=F1/A1 (A1=Area of Piston 1). As per Pascal's law, the same pressure will be transmitted throughout the container and will exert at the Piston 2. So, Pressure at Piston 2, P2=P1.
