Pascal’s principle

Pressure is the force per unit area exerted by or on a fluid. In a static fluid the pressure increases with depth, but according to Pascal s principle it is the same in all directions at any given depth. Pressure may be specified as either absolute, or gauge, the relationship between the two being ... 

Pascal s principle when a liquid or gas is pushed on by aforce, it transmits the force to all parts ot the fluid, density the amount of matter in a given space, or mass divided by volume, mass the amount of matter or stutf in something. On Earth, the mass of something is very close to its weight. 

Pascal s Principle when a liquid or gas is pushed on by a force, it transmits the force to all parts of the fluid. 

Suppose we have a confined fluid at a given pressure and decide to increase the pressure of the fluid. What happens Pascal s principle gives us the answer ... 

Pascal s principle can easily be understood by examining the pressure versus depth equation. Let s assume we have a confined fluid system where the pressure on top of the fluid is atmospheric pressure. Assuming point P1 is at the top of the fluid, the pressure at any point P2 will initially be ... 

Pascal s principle states that a change in pressure on an enclosed, incompressible fluid is transferred equally throughout the body of the fluid.

Pascal s Principle of Hydrostatics. Pascal actually has three separate principles of hydrostatics. When a textbook refers to Pascal s Principle it should specify which is meant. 

Some of these textbooks do indicate that Pascal s principle applies only to changes in pressure, but do so in the surrounding text, not in the bold, highlighted, and boxed statement of the principle. Students, of course, read the emphasized statement of the principle and not the surrounding text. Few books give any examples of the principle applied to anything other than enclosed liquids. The usual example is the hydraulic press. Too few show that Pascal s principle is derivable in one step from Bernoulli s equation. Therefore students have the false impression that these are independent laws. 

Pascal s pressure lawA law that states that the pressure applied to a fluid is transmitted equally in all directions. It is also known as Pascal s principle. 

Pascal s own discussion of the principle is not concisely stated and can be misleading if hastily read. See his On the Equilibrium Of Liquids, 1663. He inroduces the principle with the example of a piston as part of an enclosed vessel and considers what happens if a force is applied to that piston. He concludes that each portion of the vessel is pressed in proportion to its area. He does mention parenthetically that he is excluding the weight of the water..., for I am speaking only of the piston s effect. ... 

Pascal s Law Pascal s law states When there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container. We can apply Pascal s law to both liquids and gases (both hydraulics and pneumatics). The principle... 

Pascal, Blaise (1623-62) French mathematician and physicist. An infant prodigy, he had aheady made a mechanical calculating machine by 1642. in physics he formulated Pascal s law concerning fluid pressure and the principle behind the hydraulic press. The Si unit of pressure is named after him.
