Fundamentals of Fluid Mechanics Questions and Answers  


If there is a virtual mass caused by the rotation of cylinder, then this has to be included in the calculation whether small or large.




Yes the virtual mass concept only applies when there is an acceleration of the cylinder.




This is not in vector form. Acceleration is a vector and you should use the same force vector you found in part (a).




I rephrased the question, have a look at it again.






OK.



$\pi$
