  Density article - Density density (disambiguation) Greek mass volume divided iron water - What-Means.com   (Site not responding. Last check: 2007-11-01)
Formerly mass and volume were linked by defining the gram to be the mass of one cubic centimeter of water at 4°C which meant that water had density 1 kg/litre.
However, using one cubic centimetre of water as a standard for one gram is problematic due to the possibility of mass loss from evaporation as well as changes in density with temperature.
A cubic metre of water thus weighs approximately one metric tonne.

 Tsunami - Wikipedia, the free encyclopedia
The tsunami that struck Malé in the Maldives on December 26, 2004.
Waves are formed as the displaced water mass moves under the influence of gravity and radiate across the ocean like ripples on a pond.
Most of the damage is caused by the huge mass of water behind the initial wave front, as the height of the sea keeps rising fast and floods powerfully into the coastal area.

 Water Mass Variations in the Subtropical North Pacific
HOT Results: Water Mass Variations in the Subtropical North Pacific Since October, 1988, investigators at the University of Hawaii have been conducting a deep-ocean observational project, the Hawaii Ocean time-series (HOT), funded by NSF as part of the U.S. contribution to the WOCE and JGOFS programs.
The interior of the North Pacific subtropical gyre is supposed to be a region of rather small horizontal gradients of water mass properties such as salinity, dissolved oxygen and inorganic nutrients, whose temporal variations are thus expected to be slow.
Moving down in the water column, at a density of approximately 26.7 kg/m^3 we find the water mass known as North Pacific Intermediate Water, which is identified by a vertical salinity minimum.

 Steam generation system mass and feedwater control system - Patent 5406915
This is the ratio of mass flow in the downcomer 40 to the mass flow of steam leaving the steam generator through the outlet 36.
Another object of the invention is to achieve the aforementioned objects by controlling the mass of water in the steam generator for respective power conditions of the system or for respective density and flow conditions in the downcomer.
The mass in the steam generator 9 is a function of the level of the water in the narrow range and the downcomer and the level in the riser section.

 TOS 1998 poster: water mass formation   (Site not responding. Last check: 2007-11-01)
The high temperature surface water was traditionally believed to be advected into the Bight from the Leeuwin Current, a poleward eastern boundary current which flows along the continental shelf edge of Western Australia (Tomczak and Godfrey, 1994).
A sequence of satellite images (Figure 3) reveals that the origin of the warm surface water mass is an extensive shallow region in the north west of the Bight.
The process of local water mass formation and eastward advection of the warm water was verified through numerical modelling which forced the Bight with a surface heat flux and a wind stress field corresponding to the west to east passage of anticyclones.

 Mass, Volume, Alcohol, Water   (Site not responding. Last check: 2007-11-01)
However, the volume that results from a combination of different liquids may or may not be additive because the things dissolving may produce solutions whose volume may be slightly more or less than the sum of the individual components.
In the case of ethanol (alcohol) and water the volume of some concentrations is less than the sum of the components.
Liquid water has a somewhat "open" structure that is broken up by the addition of ethanol so the mixture "collapses".

 Climatic conditions
Besides the general synoptical situation and the features of local air mass circulation, the directions and the speeds of the air currents are influenced by the location of the mountain ranges.
In January, when the water of Baikal is cold and is mixed constantly by wind waves, the overcooled water provokes formation of intro-water grained ice with crystals having the shapes of dice, needles, lentils, peas, and ranging in size from 1-2 to 10-20 millimetres in diameter.
The temperature of water when this occurs is -0.2°C - -0.4°C. This results in the rustle mass, mostly in the wave-surf zone, near the shore.

 Water mass distribution and spreading
The water properties of the AAIW are nearly independent of the longitude when compared with the considerable northward increase of salinity and potential temperature (Figs.
The potential vorticity of a water parcel is conserved as long as no influence from the sea surface or mixing with water of different potential vorticity occurs.
The rather homogeneous potential vorticity distribution in the gyre indicates that the recirculation dominates the spreading of the AAIW, whereas the influence of the water inputs from the Pacific and Indian Oceans is relatively small.

 Water mass stability reconstructions from greenhouse (Eocene) to icehouse (Oligocene) for the northern Gulf Coast ...
We have developed a new method by which to reconstruct the ancient shallow water mass stability on the continental shelf using oxygen isotope variation within mollusc shells and fish otoliths and applied the method to an important interval in Earth history, the most recent transition from Greenhouse (Eocene) to Icehouse (Oligocene) climate modes.
Significant cooling (∼5°C) of the TBST at this transition indicates that the greater cooling of deeper water relative to surface water caused the increase in water mass stability.
The changes in water column structure at this transition were the most likely cause of a major extinction of planktonic foraminifera from warm to cold water taxa.

 Water Mass Black Sea
The concepts of the formation of Cold Intermediate Water (CIW) in the Black Sea are revisited on the base of numerical simulations with modular ocean model (MOM) for the period July 1991—June 1995 and validated against the data from three basin-wide surveys carried out during the same period.
The regionalization of the rate of cold water mass formation demonstrates that the dynamical control is of utmost importance.
The year-to-year variability of that rate could reach about the half of annual mean values, and the magnitude of the interannual signal of the temperature in the core of Cold Intermediate Layer is comparable with the magnitude of the seasonal one.

 Seasonal-to-interannual water mass formation in the upper tropical Indian Ocean
An ocean general circulation model coupled to an atmospheric boundary-layer model is used to investigate the seasonal cycle and interannual anomalies of water mass transformation in the upper tropical Indian Ocean.
The seasonal cycle of thermocline water mass transformation in the Indian Ocean is associated with surface density fluxes and interior mixing.
Interannual variability in the tropical Indian Ocean generates diabatic changes of water mass characteristics in the upper ocean with significant anomaly amplitudes in the formation of thermocline water for the 1982-1998 period (+6 Sv to −4 Sv).

 Air Entrapment by a Falling Water Mass   (Site not responding. Last check: 2007-11-01)
ABSTRACT: The impact of a nearly cylindrical water mass on a water surface is studied both experimentally and theoretically.
The experiments consist of the rapid release of the water from the bottom of a cylindrical container suspended above a large water tank and of the recording of the free-surface shape of the resulting crater with a high speed camera.
A bubble with a diameter of about twice that of the initial cylinder remains entrapped at the bottom of the crater when the aspect ratio and the energy of the falling water mass are sufficiently large.

Swift's X-ray data shows more water was released and over a longer time scale than had previously been thought.
The radiation traces the interaction between the neutral water molecules and the solar wind, the stream of charged, heavy particles that continually billow away from the Sun.
The X-ray power output depends on both the water production rate from the comet and the local conditions of the solar wind in the vicinity of the comet, which at the time was about 130 million km from Earth.

 Wintertime water mass transformation in the Aegean Sea   (Site not responding. Last check: 2007-11-01)
As the thermal stratification in the upper waters weakens during wintertime, the primary barrier to local deep water formation in the 1960's or in 1995 was a layer of low salinity intermediate water at 400 to 800 m depth that separates high salinity surface water from high salinity deep water.
In 1987, the low salinity intermediate water was nearly absent and typical wintertime net evaporation could then lead to local deep water formation.
Based on 1987 hydrographic conditions and observed wintertime air-sea exchanges, formation of new deep water in the Aegean Sea is likely to have occurred during the severe winters of 1991 to 1993 in the absence of low salinity intermediate water.

 ePrintsUQ - Understanding Air-Water Mass Transfer at Rectangular Dropshafts
Although similar trends were seen in both model and prototype, scale effects were observed in terms of particle residence times and bubble swarm depths.
In the prototype, detailed air-water flow measurements were performed in the shaft pool and the mass transfer equation was integrated using measured interfacial areas and particle residence times.
The results demonstrate that the air-water mass transfer is the largest at low flow rates (regime R1) because of large residence times and significant interfacial area.
