In the countries of the former USSR, 65 kg/m (131 lb/yd) rails and 75 kg/m (151 lb/yd) rails (not thermally hardened) are common. Thermally hardened 75 kg/m (151 lb/yd) rails also have been used on heavy-duty railroads like Baikal–Amur Mainline , but have proven themselves deficient in operation and were mainly rejected in favor of 65 kg/m ...
Unlike its predecessors, there exists no conversion to use the grenade cartridge of the 7,5 cm Pak 40 with a larger propellant charge to improve armor penetration capabilities. This is because in case of the M1936 F-22 and the M1939 F-22 USV the increased recoil was counteracted by adding a muzzle brake, which was not possible for the ZiS-3 ...
The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]
For example, the French livre, until 1812, had a mass of 489.5 g (1.079 lb), whilst the contemporary English (avoirdupois) pound massed of approximately 454 g (1.001 lb). Thus, a French 32-pounder at the Battle of Trafalgar threw a shot with 1.138 kg (2.51 lb) more mass than an English 32-pounder.
A 150-seat A320 burns 11,608 kg (25,591 lb) of jet fuel over 2,151 nmi (3,984 km; 2,475 mi) (between Los Angeles and New York City), or 2.43 L/100 km (97 mpg ‑US) per seat with a 0.8 kg/L fuel. [66] Its wing is long and thin, offering better aerodynamic efficiency because of the higher aspect ratio than the competing 737 and MD-80.
Molecular weights of the species in the representative octane combustion are 114, 32, 44, and 18 for C 8 H 18, O 2, CO 2, and H 2 O, respectively; therefore one kilogram (2.2 lb) of fuel reacts with 3.51 kilograms (7.7 lb) of oxygen to produce 3.09 kilograms (6.8 lb) of carbon dioxide and 1.42 kilograms (3.1 lb) of water.
Erdkamp estimates a minimum annual requirement of 150,000 tonnes, assuming an annual consumption of 200 kilograms (440 lb) per capita by a total population estimated at 750,000 to 1,000,000. [25] Mattingly and Aldrete estimate the imported grain at 237,000 tonnes for 1,000,000 inhabitants, providing 2,326 calories daily per person from grain alone.
The rover stood 135 centimetres (4 feet 5 inches) high and had a mass of 840 kg (1,850 lb). It was about 170 centimetres (5 feet 7 inches) long and 160 centimetres (5 feet 3 inches) wide and had eight wheels each with an independent suspension, electric motor and brake. The rover had two speeds, about 1 and 2 km/h (0.62 and 1.24 mph).
