Black powder substitutes are formulated to be a volume-for-volume equivalent of black powder, not an equivalent mass-for-mass (weight-for-weight). Black powder substitutes are measured by volumetric measurement techniques, not in grains on a scale, due to the difference in density compared to black powder.
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]
= 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.
See Weight for detail of mass/weight distinction and conversion. Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.
[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.
With a weight of 4.2 t (4.1 long tons; 4.6 short tons), the M777 is 41% lighter than the 7.154 t (7.041 long tons; 7.886 short tons) M198 howitzer it replaces. [ 16 ] [ 17 ] Much of the weight reduction is due to the extensive use of titanium . [ 18 ]
