There is a U-tube which contains pure water of about half of its volume. And let's put a capacitor around one surface of the water in the tube. If we apply a high dc voltage to the capacitor, the surface of the water in one side of the tube rises slightly because the permittivity of water is eighty times greater than that of air in the room temperature. And here is the question. If we make small holes on both sides of the tube and connect the holes using a small tube so that the water can circulate through, then will the water really circulate? If we ignore the viscosity of the water and the friction with the tube, will it work perpetually?
