Steam Ejector or Injector System: Working Principle Explained
The principle of operation for a steam ejector or steam injector system is based on Bernoulli''s Principle. This states that when the velocity of a fluid increases, its pressure decreases. In simpler terms, it can be stated that a high-velocity jet of vaporized liquid (usually water) is used to "eject" or "inject" the product (usually

11.2 Groundwater Flow – Principles of Earth Science
The actual velocity of the water is how fast the water must move through the pores in order to get the same flux — m3/s m2 m 3 / s m 2 — through the open area (total area × porosity). So the equation to estimate flow velocity is as follows: V = K×i n V = K × i n. where V is the velocity of the groundwater, and n is the porosity
