Pressure exerted by two liquids and its application pascal's law
Answers
Pascal's principle applies to all fluids, whether gases or liquids. A typical application of Pascal's principle for gases and liquids is the automobile lift seen in many service stations (the hydraulic jack). The oil, in turn, transmits the pressure to a piston, which lifts the automobile.
Pascal's principle is defined as
A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid.
This principle is stated mathematically as:
{\displaystyle \Delta P=\rho g(\Delta h)\,} \Delta P=\rho g(\Delta h)\,
{\displaystyle \Delta P} \Delta P is the hydrostatic pressure (given in pascals in the SI system), or the difference in pressure at two points within a fluid column, due to the weight of the fluid;
ρ is the fluid density (in kilograms per cubic meter in the SI system);
g is acceleration due to gravity (normally using the sea level acceleration due to Earth's gravity, in SI in metres per second squared);
{\displaystyle \Delta h} \Delta h is the height of fluid above the point of measurement, or the difference in elevation between the two points within the fluid column (in metres in SI).
