The Trent 800 is the lightest of the three powerplants as it weighs 13,400 lb (6.078 t) dry, [167] while the GE90 is 17,400 lb (7.89 t), [168] and the PW4000 is 16,260 lb (7.38 t). [ 169 ] [ 166 ] For Boeing's second-generation 777 variants (777-300ER, 777-200LR, and 777F) greater thrust was needed to meet the aircraft requirements, and GE was ...
The most successful variant is the 777-300ER with 799 aircraft delivered and over 844 orders to date. [7] Emirates operates the largest 777 fleet with 148 aircraft. [7] FedEx Express operates the largest fleet of the 777F cargo aircraft. As of April 2024, 2,268 Boeing 777s, of all variants, have been ordered and 1,729 have been delivered. [8]
Therefore, it is often substituted at a 1:1 ratio by volume for black powder. [4] Pyrodex is similar in composition to black powder (which consists of potassium nitrate, charcoal, and sulfur) [5] but incorporates several other compounds: [6] [7] 45% potassium nitrate; 9% charcoal; 6% sulfur; 19% potassium perchlorate; 11% sodium benzoate; 6% ...
= 10 parts per million by volume = 10 ppmv = 10 volumes/10 6 volumes NO x molar mass = 46 kg/kmol = 46 g/mol Flow rate of flue gas = 20 cubic metres per minute = 20 m 3 /min The flue gas exits the furnace at 0 °C temperature and 101.325 kPa absolute pressure. The molar volume of a gas at 0 °C temperature and 101.325 kPa is 22.414 m 3 /kmol.
[1]: 143–144 [7] [8] [9] Most prefixes correspond to integer powers of 1000; the only ones that do not are those for 10, 1/10, 100, and 1/100. The conversion between different SI units for one and the same physical quantity is always through a power of ten.
By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
Stock indexes drifted to a mixed finish on Wall Street as some heavyweight technology and communications sector stocks offset gains elsewhere in the market. The S&P 500 slipped less than 0.1% ...
Boeing, the largest manufacturer of airliners in the United States, released the Boeing 777 (commonly nicknamed the Triple Seven) in June 1995. [14] The 777 family includes the 777-200, 777-200ER, the 777-300, the 777-200LR Worldliner, the 777-300ER, and the 777 Freighter. The -100 wasn't continued in production due to loss of interest.
