Homework Statement
At What temperature will air get a larger kinematic viscosity than crude oil?
Please explain step by step.
I believe we have compare the viscosity of air and the oil using the formula: kinematic viscosity = dynamic viscosity / density
Homework Equations
inematic viscosity = dynamic viscosity / density
density = pressure / RT
The Attempt at a Solution
so what I did so far was make the kine viscosity (of air) = kine viscosity (of oil)
dynamic viscosity / (pressure / RT) = dynamic viscosity / (pressure / RT)
NOW I AM STUCK! I do not know what values to use for dyn viscosity, pressure, R. I know I have to solve for T to get the answer.
(the answer is greater than 7 but no clue how to reach there w/o those values)
