  • fluid
  • The pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. (dictionary.com)
  • Hydrostatic pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above. (dictionary.com)
  • The pressure due to the weight of fluid. (jove.com)
  • The hydrostatic pressure term in the Bernoulli equation (ρgz) decreases with fluid depth. (physicsforums.com)
  • In that example, we did not explicitly model the fluid, but added an equation to solve for the pressure, assuming incompressibility of the fluid. (comsol.se)
  • Here, we will extend this approach and include the hydrostatic pressure of the fluid in the deforming container. (comsol.se)
  • As the balloon is squeezed, the location of the highest point and the depth of fluid changes, altering the hydrostatic pressure distribution. (comsol.se)
  • where \rho is the density of the fluid, g is the force of gravity, z_0 is the location of the top of the container, and p_0 is the pressure of the fluid at the top of the container. (comsol.se)
  • Since the balloon is filled with an incompressible fluid, the pressure, p_0 , will increase as we squeeze it with the indenter. (comsol.se)
  • Ideally, this second pressure load would be based upon the depth of the fluid, but this depth is a variable that we don't know. (comsol.se)
  • So, although we are only solving for a single additional variable, P_0 , it accounts for two physical effects: the change in pressure due to the volume constraint as well as the change in the z-location of the top of the fluid. (comsol.se)
  • variations
  • Elevated intraocular pressure has been proposed to be an important risk factor for the development of glaucomatous optic neuropathy 7 8 and many ocular cells are exposed to constant variations of intraocular pressure, which generate mechanical forces affecting cell behaviour. (bmj.com)
  • temperature
  • Is it because, if being boiled over a stove-top, the temperature source is heating the vapor in the bubbles to a pressure above atmospheric? (physicsforums.com)
  • If the bubble forms at the bottom of the pot, the pressure inside the bubble will be102kPa, and it will form at the slightly higher temperature. (physicsforums.com)
  • Prokaryotes inhabiting in the deep sea vent ecosystem will thus experience harsh conditions of temperature, pH, salinity or high hydrostatic pressure (HHP) stress. (springer.com)
  • Incubations were carried out over a period of 10 days, simulating the changes in temperature and pressure in the water column of the NW Mediterranean Sea. (iddri.org)
  • deep sea
  • nov., a rod-shaped, thermo-piezophilic bacterium isolated under high hydrostatic pressure from a deep-sea hydrothermal vent. (springer.com)
  • We conclude that previousλ max measurements of deep-sea fish visual pigments, made at a pressure close to 0.1 MPa, provide a good indication ofλ max values at higher pressures when considering the ecology of vision in the deep-sea. (biologists.org)
  • We have therefore measured the visual pigment absorption spectra of extracts of rod pigments from 12 species of mesopelagic and demersal deep-sea fish when subjected to pressures of up to 54 MPa. (biologists.org)
  • structure
  • It is likely, therefore, that the pressures experienced at depth will affect opsin structure and may, thereby, affect visual pigment absorption characteristics, particularly the wavelength of maximum absorbance (λ max) . (biologists.org)
  • depth
  • If the depth of the water in the pot is 8 cm, how much hydrostatic pressure would that correspond to? (physicsforums.com)
  • The wavelength of peak absorption (λ max) was shifted to longer wavelengths by an average of 1.35 nm at 40 MPa (a pressure approximately equivalent to average ocean depth) relative to measurements made at one atmosphere (ca. 0.1 MPa), but with little evidence of a change in absorbance at the λ max . (biologists.org)
  • Nevertheless, it is possible that all such investigations have been subject to a fundamental artefact because the elevated hydrostatic pressure encountered at depth in the sea has been hitherto ignored. (biologists.org)
  • Conditions
  • A specimen is subjected to a steadily increasing pressure of water on one face, under standard conditions, until penetration occurs in three places. (iso.org)
  • The increased aggregation potential with pressure observed in these controlled conditions, may balance the loss of mineral ballast to a certain extent, although this needs to be confirmed in situ. (iddri.org)
  • sensitive
  • Our results indicated that microfilaments are more sensitive than microtubules, that both organelles became increasingly sensitive as the exerted pressure was increased and that microtubules of older embryos exhibited a better resistance. (biologists.org)
  • higher
  • Which is tiny, but is that being compensated for by an increase in pressure within the bubble or is the bubble allowed to compress while it floats up, though at a lower magnitude the higher the bubble goes. (physicsforums.com)
  • levels
  • In addition, at the end of incubation period under elevated hydrostatic pressure the recovery of adenylyl cyclase activity to control levels was examined. (bmj.com)
