Average velocity profile problem.

Hi,

I am a new comsol user and i am trying to find average velocity profile of water flowing in the pipe but i am only able to get velocity distribution in to the pipe. My question is that how can i find the average velocity of cross sections of starting and receiving end of the pipe. I have prepared a report in which i have done some simulations on velocity profile through the pipe.

Looking forward to hear from you

Best Regards
