Detonation velocity is the speed with which the detonation shock wave travels through the explosive. It is a key, directly measurable indicator of explosive performance, but depends on density which must always be specified, and may be too low if the test charge diameter is not large enough.
The P-90 is a single coil pickup designed by the Gibson Guitar Corporation. [4] [5] These pickups have a large, flat coil with adjustable steel screws as pole pieces, and a pair of flat alnico bar magnets lying under the coil bobbin. The adjustable pole pieces pick up the magnetism from the magnets.
An ignition coil is used in the ignition system of a spark-ignition engine to transform the battery voltage to the much higher voltages required to operate the spark plug(s). The spark plugs then use this burst of high-voltage electricity to ignite the air-fuel mixture. The ignition coil is constructed of two sets of coils wound around an iron ...
An induction coil consists of two coils of insulated wire wound around a common iron core (M). [1] [7] One coil, called the primary winding (P), is made from relatively few (tens or hundreds) turns of coarse wire. [7] The other coil, the secondary winding, (S) typically consists of up to a million turns of fine wire (up to 40 gauge). [8] [1] [7]
A coil with a core which is a straight bar or other non-loop shape is called an open-core coil. This has lower magnetic field and inductance than a closed core, but is often used to prevent magnetic saturation of the core. A coil without a ferromagnetic core is called an air-core coil. [14]
For this inline-4 engine, 1-3-4-2 could be a valid firing order.. The firing order of an internal combustion engine is the sequence of ignition for the cylinders.. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated.
Nord Stream (German–English mixed expression for "North Stream"; Russian: Северный поток, Severny potok) is a network of offshore natural gas pipelines which run under the Baltic Sea from Russia to Germany to provide Western Europe with natural gas. It comprises two separate projects, Nord Stream 1 and Nord Stream 2.
Smok, the Polish word for "dragon", may refer to: Michał Smok, the alias of Anna Henryka Pustowójtówna (1843−1881), Polish nationalist; Slavic dragon, a mythical creature Smok Wawelski, the Wawel Dragon, a famous dragon in Polish folklore; Smok, an extinct reptile genus; Smok, the ancestor of all living Polish Lowland Sheepdogs
