Question

an oil sample under test has a say bolt universal viscosity same as that of the std gulf oil and pannsylvanian oil at 210F their suv at 100F are 61,758 & 420sec respectively calculate vi of the sample oil brainly​

Answer 1

Answer:

An oil sample under test has a Saybolt Universal viscosity of 64 seconds at 2100F and 564 seconds at 1000F.The low viscosity standard (Gulf oil) possesses a Saybolt Universal viscosity of 64 seconds at 2100F and 774 seconds at 1000F.The high viscosity standard ( Pennsylvanian oil) gave the Saybolt Universal Viscosity values of 64 seconds at 2100F and 414 seconds at 1000F.Calculate the viscosity index of the oil under test?

Answer 2

Explanation:

L=758s

H=61s

U=420s

Therefore, V.I =L-U/L-H×100

=758-420/758-61×100

=338/697×100

=0.4849×100

=48.49
