    Can someone further explain this: The fluid heights depend upon the pressure below each column in the drainage tube. The pressure difference across the drainage tube depends upon the pressure at the reservoir end (which is due to weight of fluid) and the pressure at the exit.

    When i see that diagram, I think of the height difference caused by the difference in pressure of the column and the reservoir...

    It might help if your picture had the entire question in frame.

    The atmosphere is pushing down on the open column. More atmospheric pressure means the fluid will rise up the column less. More pressure from a heavier fluid or more fluid in a taller reservoir means fluid will rise up the column. But since the fluid has the same mass density (I'm guessing), there won't be any difference as Pressure = Rho*g*h. I believe fluid velocity would increase with a less viscous fluid.
