Question

I have to plot a graph of Pressure gradient vs average velocity (water in a pipe, I have all the data). I plan to put the average velocity on the x axis, since I could control that better in an experiment.

Do you agree/ Thanks.

Answer 1

Yes, but I wonder where you are measuring pressure (at the center of the pipe, or where). It matters. You do know that the type of pipe matters also.

Answer 2

I'm not doing the measuring, it's a graphing exercise, and I've been given the table of data. I was looking for confirmation of my choice of axes. But your extra points are well taken. Thanks for your comment.
