Pressure - Wikipedia
https://en.wikipedia.org/wiki/Pressure
Pressure is the amount of force applied at right angles to the surface of an object per unit area. The symbol for it is "p" or P. The IUPAC recommendation for pressure is a lower-case p. However, upper-case P is widely used. The usage of P vs p depends upon the field in which one is working, on the nearby presence of other symbols for quantities such as power and momentum, and on writing s…

https://simple.wikipedia.org/wiki/Pressure_in_liquidsPressure in liquids is equally divided in all directions, therefore if a force is applied to one point of the liquid, it will be transmitted to all other points within the liquid. The pressure in fluids can be calculated using the following relation: P = hρg (Pressure = Height or Depth of the liquid × Density of the liquid × Gravitational pull (9.81m/s)). Pressure is a scalar quantity. The SI Unit …

Pressure measurement - Wikipedia
https://en.wikipedia.org/wiki/Pressure_measurementPressure measurement is the analysis of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure and display pressure in an integral unit are called pressure meters or pressure gauges or vacuum gauges. A manometer is a good example, as it uses the surface area and weightof a column of li…

https://simple.wikipedia.org/wiki/Hydrostatic_paradoxPressure in liquids is equally divided in all directions, therefore if a force is applied to one point of the liquid, it will be transmitted to all other points within the liquid. Water exerts an upward force on the object and that upward force is known as buoyancy. Any object immersed in the fluid experiences buoyancy.

Partial pressure - liquids - Nexus Wiki
https://www.compadre.org/nexusph/course/Partial_pressure_-_liquidsAt constant T, the pressure could therefore be used as a stand-in for concentration (= number density). When there is a mixture of gases, each molecule of each gas contributes the same amount to the pressure, so the total pressure is the sum of the partial pressures created by each gas separately. Gases can also be dissolved in liquids.
