en.wikipedia.org/wiki/Pressure_Flow_Hypothesis

The Pressure Flow Hypothesis, also known as the Mass Flow Hypothesis, is the best-supported theory to explain the movement of sap through the phloem. It was proposed by Ernst Munch, a German plant physiologist in 1930. A high concentration of organic substances, particularly sugar, inside cells of the phloem at a source, such as a leaf, creates a diffusion gradient (osmotic gradient) that ...

The pressure flow theory states that water with food molecules inside of it moves through the phloem of a plant through pressure. This theory is meant to explain how food moves around inside plants. The pressure flow theory notes that pressure is created through water being pulled into the cells of the plant.

Mass-flow hypotheses include the pressure-flow hypothesis, which states that flow into sieve tubes at source regions (places of photosynthesis or mobilization and exportation of storage products) raises the osmotic pressure in the sieve tube; removal of sugars from sieve tubes in sink regions—i.e ...

Adiabatic flow at less than Mach 0.3 is generally considered to be slow enough. Unsteady potential flow. The Bernoulli equation for unsteady potential flow is used in the theory of ocean surface waves and acoustics. For an irrotational flow, the flow velocity can be described as the gradient ∇φ of a velocity potential φ.

What Is the Definition of Differential Pressure? by Matthew Bollinger . Differential pressure is defined as the difference of pressure measurements between two points in a system. This measurement is significant in applications that have pressure functionality, such as weather instrumentation, airplanes and cars. ...
