i'm a third year engineering student and still I haven't got rid of the maths, so a word of advice: start loving maths as you'll need it for the rest of your career.
anyway, here's my problem:

this is strictly speaking a fluid dynamics question, and usually we are given the relationship of the velocity and integrate accordingly. this time though we are given a table and are expect to use summation as a means of integration. I think i have got the hang of it but I still have some doubts, especially for the inner circle. I wrote down my difficult on the paper too.
thanks for the help gurus, much appreciated
how can i type in laTeX please? can I include diagrams also? because thats why i scanned it too so you can see what my problem is as it isn't strictly speaking mathematics problem.
or maybe some other imagehosting websites you prefer?
thanks for the replies
cheers, here it goes:
I made the image much smaller showing only the table and diagram.

Using the above table of results therfore:
Now
I am understanding more or less what is happening, but what I am not understanding is why the first part wasnt taken as since the strip is a solid circle not "hollow tubes" if you understand what i mean.
thanks
