State and Explain Pascal's law
Answers
Answer:
hlo bro here is your answer
Explanation:
Pascal's law is a principle in fluid mechanics given by Blaise Pascal that states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere. The law was established by French mathematician Blaise Pascal in 1647–48.
Answer: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. Alternate definition:The pressure applied to any part of the enclosed liquid will be transmitted equally in all the direction through the liquid.
This principle is stated mathematically as:
{\displaystyle \Delta p=\rho g(\Delta h)\,} {\displaystyle \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 meters 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 meters).
