Water Content. The quantity of water used in the mix shall be the minimum to permit proper compaction and surface finishing of the concrete. The amount of water to be added to each batch will be adjusted by the Superintending Engineer to maintain as nearly as practicable a slump of 50mm to 100mm (2" to 4") for normal reinforced concrete sections normally compacted or heavily reinforced sections compacted with vibratory equipment and slump of 100mm to 175mm (4" to 7") for sections with congested reinforcement not suitable for vibration. The total free water in each batch shall not exceed the volumes given below:- For 75mm (3”) Slump Maximum size of aggregate … 12.5mm(1/2") 20mm(3/4") 25mm(1") 37.5mm (11/2") water inO.4536Kg/2.83m3 … 1,333 1,241 1,204 1,122 (lbs./100 cubic ft.) Water in 454 litres/0.028m3 … 1.33 1. 24 1.2 1.12 (Imperial gallons/c.ft.)
Water Content. Gas delivered at the Receipt Point(s) shall be considered to be saturated with water at measurement temperature and pressure, unless Gas has been dehydrated to a water content of seven (7) Ibs/MMCF or less prior to the point of measurement. The water content shall be determined by BUYER using practices contained in GPA 181, GPA 2172, AGA Report No. 3 or other reasonable practices as determined appropriate by BUYER. Gas with seven (7) Ibs/MMCF or less shall be considered dry, i.e. containing no water
Water Content. The Water Dewpoint to be no more than minus ten degrees Celsius (-10ºC) at [insert pressure]
Water Content. Test Methods E 203 or E 1064.
Water Content. Xxxx Xxxxxxx analysis is generally the only consistently reliable procedure for the determination of water in denatured ethanol. Test Method E 203 describes the modifications required to run the test in the presence of alcohols. Specific gravity methods such as Test Methods D 891 and D 3505, are generally suitable for the reasons given in X1.2.1. Blends of fuel ethanol and gasoline have a limited solvency for water. This solvency will vary with the ethanol content, the temperature of the blend, and the aromatic content of the base gasoline. A fuel made by blending volume % fuel ethanol with a gasoline containing 14 volume % aromatics and 0.6 mass % dissolved water (about 0.5 volume %), will separate into a lower alcohol-rich aqueous phase and an upper hydrocarbon phase if cooled to about 7°C (45°F). As normal spark -ignition engines will not run on the aqueous phase material, such a separation is likely to cause serious operating problems. Because some degree of water contamination is practically unavoidable in transport and handling, and because gasoline-ethanol blends are hygroscopic, the water content of the denatured fuel ethanol must be limited when it is blended with gasoline to reduce the risk of phase separation.
Water Content. Water content (αw) is known to play an important role in affecting enzyme activity in non-aqueous environments and the thermodynamic water activity is an important variable affecting the activity of enzymes in non-aqueous solvents. The maximum initial reaction ratio was observed at αw=0.6 in the conversion of geraniol with CaL B (Xxxxxxxx et al., 2005). In the regioselective acylation of 1-beta-D-arabinofuranosylcytosine, catalyzed by i-CaL B in [C4mim][PF6], at αw=0.07, the initial rate, substrate conversion and the regioselectivity were 94.0 mM h-1, 98.5% and 99%, respectively. However, when αw = 0.85, the reaction rate was near to zero (Xx et al., 2006).
