"If there is an increase in pressure then these pressure is distributed equally through out the fluid without diminishing"

Pascal's law or the principle of transmission of fluid-pressure states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure variations (initial differences) remain the same.The law was established by Blaise Pascal.

Mathematically it is expressed as:-

 \Delta P =\rho g (\Delta h)\,
\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;? is the fluid density (in Kg/cubic meter),g is acceleration due to gravity (in m/s2).
\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 m).
