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.
The driving force in filtration is the pressure difference between the two sides of the filter. This pressure gradient pushes the liquid or gas through the filter, separating the particles based on size and allowing the filtrate to pass through while retaining the larger particles.
The Net Filtration Pressure (NFP) at the glomerulus is the difference between the net hydrostatic pressure and the blood colloid osmotic pressure acting across the glomerular capillaries. Under normal circumstances we can summarize this as NFP = NHP - BCOP or NFP = 35mm Hg - 25 mm Hg = 10mm Hg This is the average pressure forcing water and dissolved materials out of the glomerular capillaries and into the capsular spaces.
Hydrostatic equilibrium is the balance between the inward force of gravity and the outward pressure gradient in a fluid, like in a star or planet. This equilibrium prevents further collapse or expansion by ensuring that the pressure within the fluid supports the weight of the overlying material. In stars, this balance between gravity and pressure helps maintain their stable size and shape.
The primary means of water movement between fluid compartments in the body is osmosis, which involves the movement of water across semipermeable membranes to maintain a balance of fluids and solutes between compartments. Additionally, water movement can also be influenced by factors such as hydrostatic pressure and oncotic pressure gradients.
Fluid moves out of capillaries by filtration primarily due to hydrostatic pressure, which is the force exerted by the fluid within the capillaries. When the hydrostatic pressure exceeds the osmotic pressure, it causes fluid to be pushed out into the surrounding tissues. This process is influenced by the concentration of solutes; however, even at low concentrations (like mg/dL), the pressure gradient can still drive filtration. Ultimately, the balance between hydrostatic and osmotic pressures determines the net movement of fluid.

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.
Pneumatic elevators work on air pressure (similar to a bank's drive through suction tubes) and hydraulic elevators work on oil/water pressure.
Hydraulic grade line is sum of Datum + Pressure Head Energy grade line is sum of Datum + Pressure Head + Velocity Head
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.
The driving force in filtration is the pressure difference between the two sides of the filter. This pressure gradient pushes the liquid or gas through the filter, separating the particles based on size and allowing the filtrate to pass through while retaining the larger particles.
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.
