Boiler explosions are common in sinking ships once the hot boiler touches cold sea water, as the sudden cooling of the hot metal causes it to crack; for instance, when the SS Benlomond was torpedoed by a U-boat, the torpedoes and resulting boiler explosion caused the ship to go down in two minutes, leaving Poon Lim as the only survivor in a ...
The water hammer principle can be used to create a simple water pump called a hydraulic ram. Leaks can sometimes be detected using water hammer. Enclosed air pockets can be detected in pipelines. The water hammer from a liquid jet created by a collapsing microcavity is studied for potential applications noninvasive transdermal drug delivery. [33]
Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam. The term may also be applied to raw water intended for use in boilers, treated boiler feedwater , steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.
In August 1902, when maintenance was being carried out on the hydroelectrical power plant of Papigno , the closure of a water pipe caused its explosion and great damage to the plant. Allievi investigated the problem immediately thereafter and published his fundamental study on the water hammer problem the same year. He continued to study this ...
Water hammer, a pressure surge caused by a fluid suddenly changing velocity Hydrostatic shock , a hypothesized phenomenon by which pressure waves from a high-speed projectile entering a victim cause injury away from an entry wound
If a steam explosion occurs in a confined tank of water due to rapid heating of the water, the pressure wave and rapidly expanding steam can cause severe water hammer. This was the mechanism that, in Idaho, USA, in 1961, caused the SL-1 nuclear reactor vessel to jump over 9 feet (2.7 m) in the air when it was destroyed by a criticality accident ...
