What is the difference between osmotic pressure and hydrostatic pressure?

Question

This is about the exchange of substances. Thanks!

Answer 1

Osmotic pressure is the hydrostatic pressure produced by a solution in a space divided by a differentially permeable membrane due to a differential in the concentrations of solute.

Osmotic pressure is a colligative property, meaning that the property depends on the concentration of the solute but not on its identity.

Pressure in open conditions usually can be approximated as the pressure in "static" or non-moving conditions (even in the ocean where there are waves and currents), because the motions create only negligible changes in the pressure. Such conditions conform with principles of fluid statics. The pressure at any given point of a non-moving (static) fluid is called the hydrostatic pressure.

Answer 2

Hydrostatic pressure is the pressure of a certain height of liquid it has nothing to interfere directly with transport

Osmotic pressure exists when to liquids one the solvent, the second the solvent with solutes are separated by a semi-permeable membrane. So suppose you have water and you have a long tube full of an aqueous solution (containing water + different solutes) The long tube is closed by a semi permeable membrane and in contact with the Water You see that the level of water will climb in the tube until the osmotic pressure is equilibrating
