Question

I think a capillary pump that continuously moves water up and out a tube (if bent 180 degrees) is impossible because when the water gets to the end of the tube there will be no adhesive forces to continue the pull. If the end was flaired and the momentum of the liquid caused some to fall out, then more liquid would replace the liquid that fell out but because not much liquid would fall out there would not be enough momentum by the replacing liquid to cause more to fall out. Do you agree with this logic?

Answer 1

I think a capillary pump will defy thermodynamics.
