Simple function plot peculiarity

Hi guys, can someone please explain to me why the attached plots are completely wrong in MP3, whereas they are fine in M15 (where the original worksheet was built)? Obviously the MP3 plots are correct for the high Reynolds numbers, but what happens with the low Rn values? Do I need to tabulate the independent variable? Kind of beginner's question -sorry about that.

Thanks 🙂

You should have attached the worksheets. Without its hard to tell.

You may try to increase the number of points on the plot format ribbon.

Otherwise you may try a vectorized approach with the help of logspace() or logpts().

BTW, is there any specific reason for the step back from Mathcad 15 to Prime?

Is Rn defined as a vector, or are you just relying on the quickplot feature?
