What is Pascal's principle? Definition.
0:03
Pascal's principle states that when
0:05
pressure is applied to a confined fluid,
0:07
the pressure is transmitted equally and
0:10
unddeinished in all directions
0:12
throughout the fluid. Explanation:
0:14
Pascal's principle explains how pressure
0:17
behaves in liquids that are enclosed in
0:19
a container. When a force is applied at
0:22
one point in a confined fluid, the
0:24
resulting pressure spreads uniformly to
0:27
every part of the fluid and acts on the
0:29
walls of the container. This principle
0:32
is the reason why a small force applied
0:35
at one point can produce a much larger
0:37
force at another point, provided the
0:40
area is larger. It is a key idea behind
0:43
hydraulic machines. Imagine imagine
0:46
squeezing a sealed toothpaste tube. When
0:49
you press at one end, the toothpaste
0:51
comes out from the opening at the other
0:53
end. The pressure you apply spreads
0:55
through the fluid inside the tube. In
0:58
simple terms, Pascal's principle means
1:01
pressure applied to a liquid spreads
1:03
equally in all directions. Formula or
1:06
concept, Pascal's principle is expressed
1:09
using pressure relationships in fluids.
1:12
Pressure equals force/ area. In
1:15
hydraulic systems, pressure at 0.1
1:18
equals pressure at point 2. This means
1:21
forces area equals forces area where
1:25
forces and forces are applied forces.
1:28
Area and area are the areas over which
1:31
the forces act. Key points applies to
1:34
confined fluids. Pressure spreads
1:36
equally in all directions. Pressure does
1:39
not reduce within the fluid. Basis of
1:41
hydraulic machines. works only in
1:44
liquids and not gases in the same way.
1:47
Examples: hydraulic press, hydraulic
1:49
brakes and vehicles, hydraulic lifts,
1:52
syringes filled with liquid.
1:54
Applications: hydraulic braking systems,
1:57
hydraulic lifts and jacks, industrial
2:00
machines, medical syringes, physics,
2:03
education. Question: Why can a small
2:06
force lift a heavy load in a hydraulic
2:08
machine? Answer. A small force can lift
2:11
a heavy load because the pressure
2:13
applied to the fluid is transmitted
2:15
equally and a larger area produces a
2:18
larger force. Solve problem question and
2:21
answer. Question. A force of 20 un is
2:24
applied on a piston of area 0.01
2:28
m. What pressure is produced in the
2:31
fluid? Answer force equals 20N. Area
2:34
equals 0.01
2:36
m. Pressure equals force/ area. Pressure
2:40
equals 20 01.
