  2. Solution (chemistry) - Wikipedia

    Case 2: amount of solute mass is given. Case 3: amount of final solution volume is given. In the following equations, A is solvent, B is solute, and C is concentration. Solute volume contribution is considered through the ideal solution model. Case 1: amount (mL) of solvent volume V A is given. Solute mass m B = C V A d A /(100-C/d B)

  3. Pipeline transport - Wikipedia

    Pipeline transport is the long-distance transportation of a liquid or gas through a system of pipes—a pipeline—typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than 2,175,000 miles (3,500,000 km) of pipeline in 120 countries of the world.

  4. Electrical grid - Wikipedia

    The Electricity (Supply) Act 1926 led to the setting up of the National Grid. The Central Electricity Board standardized the nation's electricity supply and established the first synchronized AC grid, running at 132 kilovolts and 50 Hertz. This started operating as a national system, the National Grid, in 1938.

  5. Result - Wikipedia

    A result (also called upshot) is the final consequence of a sequence of actions or events expressed qualitatively or quantitatively. Possible results include advantage, disadvantage, gain, injury, loss, value and victory.

  6. Smart grid - Wikipedia

    The topology of the 1960s grid was a result of the strong economies of scale: large coal-, gas- and oil-fired power stations in the 1 GW (1000 MW) to 3 GW scale are still found to be cost-effective, due to efficiency-boosting features that can be cost-effective only when the stations become very large.

  7. Biogas - Wikipedia

    Biogas gas-grid injection. Gas-grid injection is the injection of biogas into the methane grid (natural gas grid). Until the breakthrough of micro combined heat and power two-thirds of all the energy produced by biogas power plants was lost (as heat).

  8. Incineration - Wikipedia

    A side effect of breaking the strong molecular bonds of dioxin is the potential for breaking the bonds of nitrogen gas (N 2) and oxygen gas (O 2) in the supply air. As the exhaust flow cools, these highly reactive detached atoms spontaneously reform bonds into reactive oxides such as NO x in the flue gas, which can result in smog formation and ...

  9. Energy policy of the United States - Wikipedia

    The United States is a net importer of natural gas, most of it by pipeline from Canada, with a smaller amount of LNG from other sources. Net gas imports into the US peaked in 2007, when the country imported 16.4 percent of the natural gas it consumed, and was the world's largest net importer of natural gas.
