  2. Diving cylinder - Wikipedia

    en.wikipedia.org/wiki/Diving_cylinder

    The pressure vessel is a seamless cylinder normally made of cold-extruded aluminum or forged steel. [5] Filament wound composite cylinders are used in fire fighting breathing apparatus and oxygen first aid equipment because of their low weight, but are rarely used for diving, due to their high positive buoyancy.

    Only the turret was the same as the Ausf. C model, with a new hull and superstructure design and the use of a Maybach HL62TRM engine driving a seven-gear transmission (plus reverse). [16] The design was shorter (4.65 m) but wider (2.3 m) and taller (2.06 m) than the Ausf. C. Speed was increased to 55 km/h. [16] A total of 43 Ausf.

    Until 1982, STP was defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 101.325 kPa (1 atm). Since 1982, STP is defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 100 kPa (1 bar). Conversions between each volume flow metric are calculated using the following formulas: Prior to 1982,

    In the first half-cycle, the first cylinder receives air from the compressor, which lasts about 3 seconds. During that time, the pressure in the first cylinder rises from atmospheric to about 2.5 times normal atmospheric pressure (typically 20 psi/138 kPa gauge, or 2.36 atmospheres absolute) and the zeolite becomes saturated with nitrogen.

    P 2 and V 2 the initial pressure and volume of the other cylinder and P 3 is the equilibrium pressure. An example could be a 100-litre (internal volume) cylinder (V 1) pressurised to 200 bar (P 1) filling a 10-litre (internal volume) cylinder (V 2) which was unpressurised (P 2 = 1 bar) (resulting in both cylinder equalising to approximately 180 ...

    en.wikipedia.org/wiki/AMX_Tracteur_C

    The tank is to be powered by 2 engines that were not specified. The tank can hold 1200 liters of fuel. The transmission is electrical. [1] [2] [3] The AMX Tracteur C design was presented to the French Army but was rejected by them in favour of the FCM F1. However, the AMX company was not disheartened and continued to work on an improved version ...
