Non-dimensionalized sutherland law

Hi, i’m Sukyung Yoon
I want to compare the compressible and incompressible flow field for the same Reynolds number condition.

Question1>
I want to simulate the Reynolds number 15,000 conditions.
Can it be said that the Reynolds number in setting (1) and (2) are the same? (chord length = 1m)
I think it’s the same, but I ask questions to be sure.

Question2)
As shown in case(3), i tried to use the all dimensionless value as in (1).
However, to use the Sutherland law, viscosity and temperature(cpTref, cpTs) were used as dimensional values.
I do not think this is consistent.
What values should I enter for viscosity and temperature?
