explain the application of Pascal 's law
Answers
Answer:
application of Pascal's principle for gases and liquids is the automobile lift seen in many service stations (the hydraulic jack). Increased air pressure produced by an air compressor is transmitted through the air to the surface of oil in an underground reservoir.
Answer:
Pascal’s Law states that the pressure applied to a fluid in a closed container is transmitted equally to all points in the fluid and act in all directions of the container. Pascal’s Law is applicable to both solids and liquids.
The law was proposed by Blaise Pascal, a French Physicist and Mathematician. He observed that when a fluid is at rest, the same amount of pressure is applied at all the points which are at the same height. Now, we get to know that pressure is not a vector quantity; and, therefore, it can not be assigned any direction. If we begin to consider that fluid is a horizontal bar with a uniform cross-section and it is in a state of equilibrium, then there will be an equal and balanced force which will be exerted at the two ends. However, if we consider that an unequal force is acting on the horizontal bar, in that case, the liquid will have some net force acting on it and it will flow. Therefore, it can rightly be said that since the liquid does not flow, it definitely has equal pressure acting on it at all the points.
The mathematical representation of the law is as follows:
F = PA; where F=applied force, P=pressure transmitted, and A=cross-sectional area.
Let us have a look at some of the examples of Pascal’s Law:
