Explain pascal's law? Write any two examples?
Answers
Answer:
Compressed air introduced to the small cylinder exerts a pressure on the surface of the oil. This pressure is transmitted by the oil to the large cylinder where the pressure acts on a large piston to produce a force large enough to lift a car. Hydraulic pumps are used widely in the automobile industry.
Explanation:
Answer:
ACCORDING TO PASCAL'S LAW:
The external static pressure applied on a confined liquid is distributed or transmitted evenly throughout the liquid in all directions”.
Explanation:
The static pressure acts at right angles to any surface in contact with the fluid. Pascal also found that the pressure at a point for a static fluid would be the same across all planes passing through that point in that fluid. Pascal’s law is also known as Pascal’s principle or principle of transmission of fluid-pressure. In 1653, Pascal law was stated by French mathematician Blaise Pascal.
FORMULA: F=PA
EXAMPLE: A pressure of 2000 Pa is transmitted throughout a liquid column due to a force being applied on a piston. If the piston has an area of 0.1 m2, what force is applied?
This can be calculated using Pascal’s Law formula.
F = PA
Here,
P = 2000 Pa = N/m2
A = 0.1 m2
Substituting values, we arrive at F = 200 N
