Static Fluid Pressure The pressure exerted by a static fluid depends only upon the depth of the fluid, the density of the fluid, and the acceleration of gravity. The pressure in a static fluid arises from the weight of the fluid and is given by the expression. P static fluid = ρgh where: ρ = m/V = fluid density g = acceleration of gravity
Hydrostatic pressure is the pressure that is exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. Hydrostatic pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above.
Sal derives the formula to determine the pressure at a specific depth in a fluid. ... The force down is going to be equal to the mass of the liquid times gravity. What is that mass of the liquid? Well, now I'll introduce you to a concept called density, and I think you understand what density is-- it's how much there is of something in a given ...
Best Answer: *Pressure=Height *Density of liquid can not be proved considering the laws of fluid mechanics. *For a particular case, you can show what you have asked. *Pressure=Height *Specific Gravity of liquid =Height *[Density of liquid] / [Density of water at 4 deg.C]

Bernoulli's equation would describe the relation between velocity, density, and pressure for this flow problem. Along a low speed airfoil, the flow is incompressible and the density remains a constant. Bernoulli's equation then reduces to a simple relation between velocity and static pressure.

The pressure exerted by a column of liquid of height h and density ρ is given by the hydrostatic pressure equation p = ρgh, where g is the gravitational acceleration. Fluid density and local gravity can vary from one reading to another depending on local factors, so the height of a fluid column does not define pressure precisely.
Vertical pressure variation is the variation in pressure as a function of elevation. Depending on the fluid in question and the context being referred to, it may also vary significantly in dimensions perpendicular to elevation as well, and these variations have relevance in the context of pressure gradient force and its effects.
Density and Specific Gravity The density (ρ) of an object or material sample is equal to its mass (m) divided by its volume (V). ρ = m— V The specific gravity (SG) of a material is equal to its density divided by the density of pure water. The specific gravity is greater than one for materials that are
