Hydrostatic pressure is defined as. “The pressure exerted by a fluid at equilibrium at any point of time due to the force of gravity”. Hydrostatic pressure is proportional to the depth measured from the surface as the weight of the fluid increases when a downward force is applied.

Hydrostatics is a subcategory of fluid statics, which is the study of all fluids, both compressible or incompressible, at rest. Hydrostatics is fundamental to hydraulics, the engineering of equipment for storing, transporting and using fluids.
Pascal’s Law. The French mathematician Blaise Pascal (1623 – 1662) states that the pressure is the same in all directions at any point in a fluid at rest. From the figure shown below, summation of forces in y-direction: $\Sigma F_y = 0$ $p_2A_{ABCO} = (p_1 A_{ABED}) \cos \theta $ $p_2A_{ABCO} = p_1 (A_{ABED} \cos \theta)$
Key Takeaways. The hydrostatic law states that the rate of increment of pressure is equal to the specific weight of the fluid at any point in a static fluid system. In hydrostatic equilibrium conditions, the force exerted by the fluid is balanced by its weight.
Pascal's law (also Pascal's principle[1][2][3] or the principle of transmission of fluid-pressure) 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.

Description of a fluid element in accelerated system under body forces. A fluid element with dimensions of DC D C, dy d y, and dz d z is motionless in the accelerated system, with acceleration, a a as shown in Figure 4.1. The combination of an acceleration and the body force results in effective body force which is.
Fluid mechanics - Hydrostatics, Pressure, Buoyancy: It is common knowledge that the pressure of the atmosphere (about 105 newtons per square metre) is due to the weight of air above the Earth’s surface, that this pressure falls as one climbs upward, and, correspondingly, that pressure increases as one dives deeper into a lake (or comparable ...
