Ed, Are you sure the labels are not backwards on the two
duct pressure recovery charts?
Tracy
Labels are correct, however, I used two
different Y scales for the dynamic pressure on the two charts. The
dynamic pressure values are correct but the unequal scales appear to give
the parabolic curve the greater dynamic pressure recovery, when in reality
it is the streamline duct.
The Y axis on the right is for dynamic
pressure.
I just posted the two charts with their
dynamic pressure scales equal and I think it is clearer now.
