The calculation of the volume flow of the liquid is possible thanks to the physics of two-phase flow. Use. Airlift pumps are often used in deep dirty wells ...
Tectonic uplift is the geologic uplift of Earth's surface that is attributed to plate tectonics. While isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of crustal thickening (such as mountain building events), changes in the density distribution of the crust and ...
Dewatering / d iː ˈ w ɔː t ər ɪ ŋ / is the removal of water from a location. This may be done by wet classification, centrifugation , filtration , or similar solid-liquid separation processes , such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.
Where no dewatering techniques were effective the mine had to be shut down due to flooding. [3] In the 15th century mine dewatering techniques made some technical advancements as the first mechanized wooden pumps were used in the German Rammelsberg mine (Lower Saxony), and later in the Ehrenfriedersdorf (Saxony) mines in the 16th century.

In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid is the kinetic energy associated with the speed of flow of the fluid, plus energy from static pressure in the fluid, plus energy from the height of the fluid relative to an ...
EN 1997-2 is intended to be used in conjunction with EN 1997-1 and provides rules supplementary to EN 1997-1 related to planning and reporting of ground investigations, general requirements for a range of commonly used laboratory and field tests, interpretation and evaluation of test results and derivation of values of geotechnical parameters and coefficients.
The standard step method (STM) is a computational technique utilized to estimate one-dimensional surface water profiles in open channels with gradually varied flow under steady state conditions.
The pore water pressure is essential in differentiating a soil's total stress from its effective stress. A correct representation of stress in the soil is necessary for accurate field calculations in a variety of engineering trades. [3]
