Hull speed can be calculated by the following formula: where is the length of the waterline in feet, and is the hull speed of the vessel in knots. If the length of waterline is given in metres and desired hull speed in knots, the coefficient is 2.43 kn·m −½.
A Magic Triangle image mnemonic - when the terms of Ohm's law are arranged in this configuration, covering the unknown gives the formula in terms of the remaining parameters. It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = π r 2 h and τ = rF sinθ.
Displacement hull, where the moving hull's weight is supported by buoyancy alone and it must displace water from its path rather than planing on the water's surface; Displacement speed, a rule of thumb for non planing watercraft to estimate their theoretical maximum speed; Displacement (ship), the weight of a ship
chemical physics A branch of chemistry and physics that studies chemical processes from the point of view of physics by investigating physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics. chromatic aberration circular motion classical mechanics. Also called Newtonian mechanics.
Royal Navy World War II motor torpedo boat planing at speed on calm water showing its hard chine hull - note how most of the forepart of the boat is out of the water. At rest, a vessel's weight is borne entirely by the buoyant force. Every hull acts as a displacement hull at low speeds: the buoyant force is mainly responsible for supporting the ...
There are many hull types, and a builder should choose the most appropriate one for the boat's intended purpose. For example, a sea-going vessel needs a hull which is more stable and robust than a hull used in rivers and canals. Hull types include: Smooth curve hull: these are rounded and free of chines or corners.
Standard displacement, also known as "Washington displacement", is a specific term defined by the Washington Naval Treaty of 1922. [11] "It is the displacement of the ship complete, fully manned, engined, and equipped ready for sea, including all armament and ammunition, equipment, outfit, provisions and fresh water for crew, miscellaneous ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
