Fundamentals of Fluid Mechanics Questions and Answers  


I think I gave more than enough hints for this question. You should be able to figure the rest out on your own.




Yes, I see no problem.






Correct. I'll change the submission date to the following Tuesday.




Yes, the units for $Q$ will be the same either in the example problem in class or in this problem.




Is it mentioned in the problem statement that $Q=Uh$? If not, then it is most probably not equal to this.




Yes, from now the office hours are every Monday from 12 pm and from 56 pm.




The pressure will change at $r=R$ because $v_{\theta}$ changes. First find $v_{\theta}$ at $r=R$.




Using the cylinder fundamental solution is ok to find the pressure on some parts of the body, but not on all.




Try solving it in cylindrical coordinates instead of cartesian. You should be able to find what $r$ is.




The difficulty of this problem is not so much doing the integration but setting up the integral properly. And this becomes a fluid problem.. You need good understanding of fluid physics to know how to set up such an integral properly. So no, we should keep this problem for the final exam.




No, this problem is kept and is important. You should know how to integrate pressure forces over a portion of a cylinder.




This is not a proper reason to exclude a problem and I don't think this is a very lengthy problem. You should be able to easily answer this within 3035 minutes because you should have worked it out already.
