10.16 cm = 1.016 dm – 1 hand used in measuring height of horses (4 inches) 12 cm = 1.2 dm – diameter of a compact disc (CD) (= 120 mm) 15 cm = 1.5 dm – length of a Bic pen with cap on; 22 cm = 2.2 dm – diameter of a typical association football (soccer ball) 30 cm = 3 dm – typical school-use ruler length (= 300 mm)
The instrument exhibited a peak detection wavelength of 7.5 micrometers for positive bias at 10 K when the electrons resided in one of the quantum wells and switched to 8.8 micrometers at a large negative bias when the electrons were transferred to the other well. [7] [8]
The 8.8 cm KwK 36 was derived from the 8.8 cm Flak 36 anti-aircraft gun by adapting/modifying it to the limited space available in tank turrets. Parts of the KwK 36 were built to practically the same design as the 75-millimetre (3.0 in) and 50-millimetre (2.0 in) guns already used in German tanks.

The SK C/30 had a barrel and breech end-piece with a half-length loose liner and a vertical sliding breech block. The SK C/30 guns were mounted on a hand-operated MPLC/30 mounting that had a total weight of 5,760 kilograms (12,700 lb) including a 15–10 millimetres (0.59–0.39 in) shield and a fuze-setting machine.
At 6.24 m (20.5 ft), the length of the KwK 43's barrel was over 1.3 metres longer than of that of the 8.8 cm KwK 36 used for the Tiger I.The cartridge of the KwK 43's shell was also considerably longer (at 82.2 centimetres (32.4 in)) and wider than that of the KwK 36's, meaning that the KwK 43 allows for more room for a heavier propellant charge in its cartridge case than the KwK 36 could.
The Womersley number, usually denoted , is defined by the relation = = = =, where is an appropriate length scale (for example the radius of a pipe), is the angular frequency of the oscillations, and , , are the kinematic viscosity, density, and dynamic viscosity of the fluid, respectively. [2]
The 8.8 cm SK L/30 was a widely used naval gun on World War I pre-dreadnoughts, cruisers, coastal defence ships, avisos, submarines and torpedo boats in both casemates and turrets. Its primary use on pre-dreadnoughts, cruisers and coastal defence ships was as an anti-torpedo boat gun, while on avisos, submarines and torpedo boats it was their ...
