Hydrostatic pressure is the pressure of a "standing liquid" and hydraulic pressure is the pressure in a fluid system that is being acted on by a compressor or pump. Let's look more closely. Let's say we're on a boat on the ocean and we slide over the side and into the water. We can feel the water pressure on us. As we move deeper into the water, that is, we dive deeper, the hydrostatic pressure increases. If we took ping pong balls with us as we dove deeper, they'd eventually be crushed by hydrostatic pressure. The pressure can be looked at as the weight of the water column (due to its height) on whatever is submerged. In a hydraulic system, a pump pressurizes the system to some level set by the controller and the safety (pressure release) systems. Some systems operate at pressures that are out of sight because they are so high. The hydraulic pressure is "artificial" in that a pump created it, and hydrostatic pressure is "natural" and is created by the weight of the column of the liquid creating it.
Water potential is the potential pressure of water relative to pure free water (e.g. deionized water) in reference conditions. It quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects including surface tension. Water potential is measured in units of pressure and is commonly represented by the Greek letter Ψ (Psi). Typically, pure water with standard temperature and pressure (or other suitable reference condition) is defined as having a water potential of 0. The addition of solutes to water lowers its potential (makes it more negative), just as the increase in pressure increases its potential (makes it more positive). If possible, water will move from an area of higher water potential to an area that has a lower water potential.
One very common example is water that contains a dissolved salt, like sea water or the solution within living cells. These solutions typically have negative water potentials, relative to the pure water reference. If there is no restriction on flow, water molecules will proceed from the locus of pure water to the more negative water potential of the solution.
Osmosis may be opposed by increasing the pressure in the region of high solute concentration with respect to that in the low solute concentration region. The force per unit area, or pressure, required to prevent the passage of water through a selectively-permeable membrane and into a solution of greater concentration is equivalent to the osmotic pressure of the solution, or turgor. Osmotic pressure is a colligative property, meaning that the property depends on the concentration of the solute but not on its identity.
Increasing the pressure increases the chemical potential of the system in proportion to the molar volume (δμ = δPV). Therefore, osmosis stops when the increase in potential due to pressure equals the potential decrease from
hydrostatic pressure - drives fluid out
osmotic/oncotic pressure - solute/protein concentration that draws fluid in

The movement of water and electrolytes is primarily regulated between fluid compartments by hydrostatic pressure and osmotic pressure.
is the same
the pressure ;)
gfr is the net results of the balance between hydrostatic pressures &colloid osmotic pressures of intra vascular compartment & within the Bowman's capsule,where the net pressure gradient is towards filtration.i.e. "Net filtration pressure".Any method which will reduce this net filtration pressure will reduce GFR.That can be achieved by increasing the plasma globulin ad albumin level(increase colloid osmotic pressure),hypotension and addition of vasocostrictor at afferent and vasodialtors at efferent tubule(reducing capilary hydrostatic pressure) or obstructing the free flow of urine(increasing Bowman's casular hydrostatic pressure)
there is no difference between high pressure and performance chromatography
hydraulics uses the principle of hydrostatic pressure to work
is the force responsible for moving fluid across capillary walls. It is the difference between net hydrostatic pressure and net osmotic pressure. NFP= Net hydrostatic pressure - net osmotic pressure

Hydrostatic and osmotic pressure.
Any pressure difference is irrelevant. The distinction is in the operating fluid. In pneumatic systems, it's a gas. In hydraulic systems, it's a liquid.
Hydraulic grade line is sum of Datum + Pressure Head Energy grade line is sum of Datum + Pressure Head + Velocity Head
Pneumatic elevators work on air pressure (similar to a bank's drive through suction tubes) and hydraulic elevators work on oil/water pressure.
Hydrodynamics means the branch of science that deals with the dynamics of fluids, especially incompressible fluids, in motion or the dynamics of fluids in motion. Hydrostatic in relation to fluids that are not moving in Room, Temperature, Pressure.
We estimate the pressure difference (specifically due to hydrostatic effects) as follows:Δp = ρgΔh =(pgh1-pgh2)(1.06 × 103 kg/m3) (9.8m/s2) (1.83 m-0) =1.90 × 104 Pa .
There is no difference that I am aware of. These terms seem to be used interchangably.
one is punomatic and one is hydromatic and that is all
Pneumatic pressure testing of pressure vessels is done to check the leakage for any leakage where as hydraulic pressure testing is done to check the vessel for its strength.
