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.
A 68 kg (150 lb) person walking at 4 km/h (2.5 mph) requires approximately 210 kilocalories (880 kJ) of food energy per hour, which is equivalent to 4.55 km/MJ. [ 15 ] 1 US gal (3.8 L) of petrol contains about 114,000 British thermal units (120 MJ) [ 52 ] of energy, so this is approximately equivalent to 360 miles per US gallon (0.65 L/100 km).
While the external payload remained at 24 of 500 pounds (230 kg) or 750 pounds (340 kg) bombs, the internal capacity increased from 27 to 84 for 500 lb (230 kg) bombs, or from 27 to 42 for 750 lb (340 kg) bombs. [168] The modification created enough capacity for a total of 60,000 pounds (27,000 kg) using 108 bombs.
Below that temperature, but above the freezing point of 0 °C (32 °F), it expands becoming less dense until it reaches freezing point, reaching a density in its liquid phase of 999.8 kg/m 3 (62.4155 lb/cu ft). Once it freezes and becomes ice, it expands by about 9%, with a density of 917 kg/m 3 (57.25 lb/cu ft).
As there are many units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per cubic metre (kg/m 3) and the cgs unit of gram per cubic centimetre (g/cm 3) are probably the most commonly used units for density. One g/cm 3 is equal to 1000 kg/m 3. One cubic ...
The fuel load was a thousand pounds heavier than any the Spirit had lifted during a test flight, and the fully loaded airplane weighed 5,200 pounds (2,400 kg; 2.6 short tons). [ 65 ] [ 66 ] With takeoff hampered by a muddy, rain-soaked runway, the plane was "helped by men pushing at the wing struts," with the last man leaving the wings only one ...
Transport costs can reach 50¢ per pound ($1.10/kg) or higher in some remote areas during times of inclement weather or rough terrain conditions, if these locations can be reached at all. The cost of delivering a gallon (3.8 L) of milk is about $3.50 in many villages where per capita income can be $20,000 or less.
