  2. Torricelli's law - Wikipedia

    en.wikipedia.org/wiki/Torricelli's_law

    Torricelli's law, also known as Torricelli's theorem, is a theorem in fluid dynamics relating the speed of fluid flowing from an orifice to the height of fluid above the opening. The law states that the speed of efflux of a fluid through a sharp-edged hole in the wall of the tank filled to a height above the hole is the same as the speed that a ...

  3. Sinking of the RMS Lusitania - Wikipedia

    en.wikipedia.org/wiki/Sinking_of_the_RMS_Lusitania

    The Admiralty then cancelled their earlier decision and decided not to use her as an AMC after all; large liners such as Lusitania consumed enormous quantities of coal (910 tons/day, or 37.6 tons/hour) and became a serious drain on the Admiralty's fuel reserves, so express liners were deemed inappropriate for the role when smaller cruisers ...

  4. Capsizing - Wikipedia

    en.wikipedia.org/wiki/Capsizing

    Capsizing or keeling over occurs when a boat or ship is rolled on its side or further by wave action, instability or wind force beyond the angle of positive static stability or it is upside down in the water. The act of recovering a vessel from a capsize is called righting. Capsize may result from broaching, knockdown, loss of stability due to ...

  5. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    Bernoulli's principle can be used to calculate the lift force on an airfoil, if the behaviour of the fluid flow in the vicinity of the foil is known. For example, if the air flowing past the top surface of an aircraft wing is moving faster than the air flowing past the bottom surface, then Bernoulli's principle implies that the pressure on the ...

    USS Regulus hard aground in 1971 due to a typhoon: after three weeks of effort, Naval salvors deemed it unsalvageable.. Marine salvage takes many forms, and may involve anything from refloating a ship that has gone aground or sunk as well as necessary work to prevent loss of the vessel, such as pumping water out of a ship—thereby keeping the ship afloat—extinguishing fires on board, to ...

    the bottom vessel is then heated; as the temperature increases, the vapor pressure of the water increases (it increasingly evaporates); when the water boils the vapor pressure equals atmospheric pressure, and as the temperature increases above boiling the pressure in the bottom vessel then exceeds atmospheric pressure, and pushes the water up ...
