Pumping water using capillary and centrifugal forces

The capillary effect is also present at the outlets, resisting the water from flowing out of the outlets. The rotation will help, but Coriolis effect will also resist rotation. How much is depending on the mass flow.

@Vidar,

Capillary  force is a very  weak  force   and  centrifugal  force  is  strong  force  hence  water  will be ejected out  of  capillary  tube  at  lower  speeds.     The effect  of  coriolis  force  at lower speeds  is negligible.
If   you want  to  verify  this  experiment,      just   soak   a sponge  in water,   fix it  to  some shaft  or   stick  at center  and  rotate  the  sponge.     You can see  water  ejecting  out  of sponge  at lower  speeds.     Effect  of coriolis force  at  that  speed is negligible.

The same can be said about the capillary effect. It is negligble in both ends. So there is no point in using the capillary effect to anything useful. And you do not gain anything by putting the system into rotation.
The capillary effect will help fluids to enter the tube with a given force. The same force is preventing the fluids to exit. The rotation will make this device into a solely centrifugal pump. These pumps can move fluid with energy input. The energy is used to pump fluids upwards. If the pump is able to move a significant amount of fluid, the Coriolis effect will be as much significant.
No gain. Sorry.
