Wasser in die Höhe pumpen

Using the lever pump water from the river to the tank situated above you. If you manage to fill the tank, the flap opens and the released water flows down the pipes to the water turbines. Notice which of the turbines rotates more quickly and through where the water is fed to the turbine. To pump water up to a height requires great effort. In the down direction water is helped by the gravitational force that we had to overcome during pumping. Water is released from the tank by the action of hydrostatic pressure, developing in the liquid due to its weight. The stream of water drives two turbines. The high head water turbine rotates faster than the low head water turbine.
