Viscosity of high viscus oil must be determined by apparatus:a.Noneb.Redwood viscometer No.1c.Redwood viscometer No.2d.Redwood viscometer No.3

An oil of unknown viscosity index has a redwood viscosity of 64 s at 210 °F and 564 s at 100 °F. The low-viscosity standard (Gulf oil) possess a redwood viscosity of 64 s at 210 °F and 774 s at 100 °F. The high-viscosity standard (Pennsylvanian oil) has a redwood viscosity of 64 s at 210 °F and 414 s at 100 °F. Calculate the viscosity index of the unknown oil.

what is viscosity

Oil Field Unit of Viscosity is :Group of answer choicesPsi.sPa/scpPa.s

An oil sample has the same viscosity as standared naphtnenic and paraffinic type oil at 2100. Their viscocities at 380C are 325 S.U.S., 430 S.U.S and 260 S.U.S respectively. Calculate the viscosity Index of oil.a.33.34b.58.3c.66.78d.61.76

An oil sample under test has a Saybolt universal viscosity same as standared gulf oil (low viscosity standard) and Pennsylvanian oil (high viscocity standard) at 2100. Their saybalt universal viscocities at 1000F are 600, 800 and 500 respectively. Calculate the viscosity Index of oil sample under test.
