Homework Statement
Hi guys, I need to explain the outlier point here, which has been shaded in the excel spread sheet when comparing the two dimensionless groups,
The dimenionsless group, drag-coefficient is given by Drag/(density*V^2*D^2)
and dimensionelss group, spin parameter, is given by omega/VD
The Attempt at a Solution

The question explicitly asks to, "explain the outlier(s)". My friend thinks that it is because the flow for the outlier point, shaded, is extremely turbulent, whereas the others all have a roughly similar reynolds number of ~20,000.
I can't explain it but I don't think this is correct. I think it has to do with the way we vary the product of the velocity and diameter of the ball.
