Seawater, or sea water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium ( Na +
In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg).
Due to the higher density of sea water (1,030 kg m −3) than air (1.2 kg m −3), the force exerted by the same velocity on an organism is 827 times stronger in the ocean. When waves crash on the shore, the force exerted on littoral organisms can be equivalent to several tons.
PEG-PPG-PEG, Pluronic P-123 ... Density: 1.018 g/mL at 25 °C ... which is hydrophobic at temperatures above 288 K and is soluble in water at temperatures below 288 K
New ship being prepared for launch, showing fresh anti-fouling paint Ship hull being cleaned of fouling in drydock. Anti-fouling paint is a specialized category of coatings applied as the outer (outboard) layer to the hull of a ship or boat, to slow the growth of and facilitate detachment of subaquatic organisms that attach to the hull and can affect a vessel's performance and durability.
Pounds per gallon, a measure of density, typically of a fluid. It is common in the oil industry, especially as a unit for Mud weight.

PPG Industries announced an agreement to acquire Glidden from AkzoNobel for $1.05 billion on December 14, 2012. The transaction closed April 1, 2013. [ 1 ] Following the deal, PPG will be the second largest paint manufacturer in North America, behind Sherwin-Williams .
T-S diagram of a station in the North Pacific. In oceanography, temperature-salinity diagrams, sometimes called T-S diagrams, are used to identify water masses.In a T-S diagram, rather than plotting each water property as a separate "profile," with pressure or depth as the vertical coordinate, potential temperature (on the vertical axis) is plotted versus salinity (on the horizontal axis).
