The Jet d'Eau (Water-Jet) is a large fountain in Geneva, and is one of the city's most famous landmarks, Situated where Lake Geneva exits as the Rhône, it is visible throughout the city. Five hundred litres of water per second are jetted to an altitude of 140 metres by two 500 kW pumps, operating at 2,400 V, consuming one megawatt of electricity. The water leaves the 10 centimetres nozzle at a speed of 200 kilometres per hour. At any given moment, there are about 7,000 litres of water in the air. 21.08.2020 © 2020 Didier Ruef
