A tornado is a violently rotating column of air, pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud.. Literally, in order for a vortex to be classified as a tornado, it must be in contact with the ground and the cloud base. Weather scientists haven't found it so simple in practice, however, to classify and define tornadoes.
Turbine Oil. any oil used to lubricate the bearings and auxiliary machinery in steam and hydraulic turbines, in turbopumps, and in air, gas, and refrigeration turbocompressors.Turbine oils are also used as lubricants and working fluids in various types of closed-cycle industrial machinery.ynthetic turbine oils based on trixylenyl phosphate are used in control systems of high-power steam turbines. The advantage of these oils is their high flame resistance, but they are expensive and somewhat toxic. Spravochnik po primeneniiu i normam raskhoda smazochnykh materialov, 3rd ed., books 1â2.
Motor oil. Motor oil, engine oil, or engine lubricant is any of various substances comprising base oils enhanced with additives, particularly antiwear additive plus detergents, dispersants and, for multi-grade oils viscosity index improvers. In addition to that, almost all lubricating oils contain corrosion (GB: rust) and oxidation inhibitors. Motor oil is used for lubrication of internal combustion engines. The main function of motor oil is to reduce friction and wear on moving parts and to clean the engine from sludge (one of the functions of dispersants) and varnish (detergents).
