A race to speed
Speed and pumps
The highest speed is the speed of light in vacuum, which reaches 299,792,458 m/s, which corresponds to 1,079,252,849 km/h. In comparison, the earth revolves around the sun at a speed of 30,000 m/s or 108,000 km/h.
2,179 km/h vs. 80,7 km/h
The Aérospatiale BAC Concorde 101/102, short Concorde, was the first supersonic airliner in scheduled passenger service. It reached a top speed of 2,179 km/h or a cruising speed of 2,158 km/h. From London to New York, the Concorde needed about 3.5 hours offering space for just over 100 passengers.
Vietnam is one of the rainiest countries in the world. The most precipitation is found in the north of the Southeast Asian coastal state. In order to contain the severe effects of the annual period of rain and heavy storms, the Vietnamese ministry of agriculture and rural development launched numerous flood control projects. The Yen Nghia project marks the beginning of this initiative. This flood discharge pumping station, which is the biggest in the country, was built to the southwest of the capital Hanoi, where about 6.4 million people live. In this station, ten ANDRITZ vertical line shaft pumps VLSP series will be in operation by May 2019. Each pump conveys up to 15 cubic meters of water per second. Their impellers achieve around 1,500 rpm, which roughly corresponds to 80,7 km/h.
Pump vs. train
574.8 km/h vs. 203,76 km/h
The highest ever achieved speed of a train (wheel/rail system) is (still) at 574.8 km/h. The TGV V-150 scored this world record on April 3, 2007.
The old Bellwood granite quarry in the northwestern part of Atlanta is to be transformed into one of the largest drinking water reservoirs in the United States, with a capacity of 9.5 billion liters of water (2.5 billion US gallons). In addition to the construction work, the project also includes building two central pumping stations that will transport the water to the population of over one million in and around the city of Atlanta. Two ANDRITZ double-suction submersible motor pumps from the HDM series will provide the necessary pump power for one of these stations. They provide a constant capacity of 4,842 m3/h (30 mgd), even under fluctuating water surfaces up to 36.6 m ( 120 ft), between minimum and maximum. The impellers of these pumps achieve 1,081 revolutions per minute each, which roughly corresponds to 203,76 km/h.
Pump vs. chess
Blitz chess is a special form of fast chess in which each side is given less than ten to fifteen minutes for the entire game. Thus, these games often do last just over five minutes. If a player overruns the overall allowed time for making moves, he/she loses the game, unless at this time the opponent has no opportunity to defer chess by a legal train sequence or even exceeded his/her own thinking time. In this case, the game ends in a tie.
In the course of an average blitz chess game, the ANDRITZ concrete volute pumps built for the Kaleshwaram project could transport up to 24,900 cubic meters of water. The Kaleshwaram Project is one of the largest subprojects of a massive Indian irrigation initiative. The project is designed to store about 4.7 trillion liters of water in order to irrigate 736,345 ha. This project comprises a dam and several pumping stations with reservoirs. Water is transported over a height of 500 m and a distance of 200 km. It is the first multi-stage lift irrigation project of this magnitude and complexity in India. It also contains the longest water transport tunnel in Asia, extending over a distance of 81 km connecting the dam to a reservoir. An irrigation project of this kind is unique, not just in India, but worldwide.
