Fundamentals of Fluid Mechanics Questions and Answers  


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.






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