The solutions are quite corrosive towards mild steel (up to 0.5 inches (1.3 cm) per year on C1010 steel) and are therefore generally equipped with a corrosion inhibitor to protect tanks, pipelines, nozzles, etc. Urea–ammonium nitrate solutions should not be combined with calcium ammonium nitrate (CAN-17) or other solutions prepared from ...
Desired product 50% helium, 16% oxygen, remainder nitrogen (34%). The PO 2 after the helium addition must be 0.16 bar if there is negligible pressure loss. The ratio of oxygen to nitrogen must be 16:34, which gives 16/(16+34) = 32% oxygen, or a 0.32 bar PO 2 for the nitrox.
Retaining nitrogen in trimix can contribute to the prevention of High Pressure Nervous Syndrome, a problem that can occur when breathing heliox at depths beyond about 130 metres (430 ft). [ 1 ] [ 15 ] [ 16 ] [ 17 ] Nitrogen is also much less expensive than helium.
Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue [3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water .
[3] [23] Since the word is a compound contraction or coined word and not an acronym, it should not be written in all upper case characters as "NITROX", [3] but may be initially capitalized when referring to specific mixtures such as Nitrox32, which contains 68% nitrogen and 32% oxygen. When one figure is stated, it refers to the oxygen ...
The world's top ethanol fuel producer in 2010 was the United States with 13.2 billion U.S. gallons (49.95 billion liters) representing 57.5% of global production, followed by Brazil with 6.92 billion U.S. gallons (26.19 billion liters), and together both countries accounted for 88% of the world production of 22.95 billion U.S. gallons (86.85 ...
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.
Working the earlier example, for a nitrox mix containing 64% nitrogen (EAN36) being used at 90 feet, the EAD is: EAD = (90 + 33) × (0.64 / 0.79) − 33 EAD = 123 × 0.81 − 33 EAD = 100 − 33 EAD = 67 feet. So at 90 feet on this mix, the diver would calculate their decompression requirements as if on air at 67 feet.
