how to integrate the velocity profile
here I plot the velocity profile. how can I integrate this velocity profile(how to integrate the area) Namely, how to integrate the curve covering the the Y axis(or the axis)? thank you for help.

Re: how to integrate the velocity profile
what i did was, i monitored the variable in engineering data and then with the help of excel i calculated area by trapazoidal/simpson's rule.
i believe there should be some easy way also,,but when i asked, everybody kept their secret weapon. 
Re: how to integrate the velocity profile
