Bulk viscosity shell
Volume viscosity (also called bulk viscosity, or dilatational viscosity) is a material property relevant for characterizing fluid flow. Common symbols are or . It has dimensions (mass / (length × time)), and the corresponding SI unit is the pascal-second (Pa·s). Like other material properties (e.g. density, shear viscosity, and thermal conductivity) the value of volume viscosity is specific to each fluid and depends additionally on the fluid state, particularly its WebProperties Method Shell Turbo Oil T 46 Viscosity @400C cSt ASTM D445 46.0 Viscosity @1000C cSt ASTM D445 6.90 Viscosity Index ASTM D2270 105 Color ASTM D1500 L 0.5 ...
