I don't get the bit about the time to flow out as this is determined by the width
  of the drain aperture, the number of spokes or holes, and - to put not too 
fine a point
on it - how clean my sink is. All of which would impede any attempt to use it to 
calculate the Coriolis Forces from the velocity of outflow.

Would be delighted to hear any more details of the project.
