hello, I have solving a 2D oil water multi phase flow in a horizontal pipe having L=4m and D=0.026, It was mention that flow are flowing with a different mixture velocity ranges 1-3 m/s and different oil cut ranges 0.1-0.9. I solved it in fluent17 and I get a exact flow pattern and I take a vertical cross section in pipe outlet where I want plot below mention variables.

My question is that (1) how I plot pressure gradient vs input oil fraction in fluent
(2)How I plot pressure gradient vs water hold up in fluent

please sir kindly look into this matter .I have in problem to solve it last 15 days.I did not solved it.Its urgent
