Jul 11, 2018 · Recent studies, however, suggest the presence of new water-bearing minerals dubbed phase D and phase H. Exactly what these minerals are like and how much water they might store remains an open question, Panero said. “Because it is a wide-open question, I think that the water content in the mantle remains open for debate — wide open.” Water lowers an oil's interfacial tension (IFT), which can cripple its air-handling ability, leading to aeration and foam. It takes only about 1,000 ppm water to turn your bearing sump into a bubble bath. Air can weaken oil films, increase heat, induce oxidation, cause cavitation and interfere with oil flow; all catastrophic to the bearing ...Many water-related problems are confronted in coal mining, and the mechanical properties of coal inevitably deteriorate due to water–rock interactions.
