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.
The hydrogen is stored in a 500-U.S.-gallon (1,900 L) tank at 200 pounds per square inch (1,400 kPa), and runs a ReliOn fuel cell to provide full electric back-up to the off-the-grid residence. Another closed system loop was unveiled in late 2011 in Hempstead, NY.
The Model 464-16 was a "nuclear only" bomber with a 10,000-pound (4,500 kg) payload, while the Model 464-17 was a general purpose bomber with a 9,000-pound (4,100 kg) payload. [21] Due to the cost associated with purchasing two specialized aircraft, the USAAF selected Model 464–17 with the understanding that it could be adapted for nuclear ...
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).
Ethanol-water mixtures have less volume than the sum of their individual components at the given fractions. Mixing equal volumes of ethanol and water results in only 1.92 volumes of mixture. [75] [80] Mixing ethanol and water is exothermic, with up to 777 J/mol [81] being released at 298 K. Hydrogen bonding in solid ethanol at −186 °C
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.
