The first guide pipe is connected to the outside of the tank. The lower part of the second guide pipe is closed and the upper part is opened. The pulley housing is located on the upper part of the first guide pipe and the second guide pipe. The pulley is located inside the pulley housing. The first plumb receives the buoyancy from the liquid flowing into the first guide pipe. The second plumb has the same mass as the first plumb. |
