What Is Stress Physiology?
Osmotic pressure, also called dynamic water pressure, refers to the pressure of water on a unit volume of soil in the direction of infiltration, and the unit is kilonewtons / cubic meter. In basic chemistry, osmotic pressure refers to the minimum pressure applied above the solution in order to maintain the osmotic equilibrium when the pure solvent is separated from the solution by a semi-permeable membrane.

- Explanation 1: Osmotic pressure, also known as hydrodynamic pressure, refers to the pressure of water on a unit volume of soil in the direction of infiltration, and the unit is kilonewtons / cubic meter. The influence of osmotic pressure on the stability of rock and soil varies with different seepage directions. For example, when the seepage direction under the dam foundation is consistent with gravity, the seepage force can improve the stability of the rock and soil; if it is opposite to the direction of gravity, it will reduce the pressure between the particles, which will produce

- Explanation: osmotic pressure, a special term for plant physiology. As its name implies, it refers to the physiological burden that plants (especially plant leaves) face when facing the physiological process of infiltration. Within a standard atmospheric pressure and a certain solution concentration range, it changes inversely with the osmotic potential and has nothing to do with the nature of the plant tissue itself.

- LP \ 39450 or osmometer-030 are commonly used in scientific research for determination. During use, care should be taken not to generate air bubbles in the measuring tube. If air bubbles are generated, a small amount of Bicatinff standard reagent can be added for adjustment.
- p (osmotic pressure) = 1 / C T
- Note: T is the absolute temperature in Kelvin .
- is the osmotic pressure coefficient, the unit is Lambert (Lp: lamport), and the value is usually 8.53 under standard conditions.
- Osmotic pressure is a concept completely opposite to osmotic potential. In short-osmotic potential represents osmotic capacity, and osmotic pressure represents the degree to which plant tissues cannot penetrate into solutions of different concentrations.
- This concept is often used when studying plant physiology under stress conditions such as drought. [2]
- It should be noted that the concept of osmotic pressure in plant physiology should be distinguished from the concept of osmotic pressure in chemical and engineering geology. When doing research and calculations in chemistry, engineering geology and other disciplines, Lambert should be converted to molar concentration calculations.
