2 imperial pints, 1 imperial quart, or a quarter of an imperial gallon. Referred to as a "40" or “40-pounder” in Canada (as in 40 Imperial ounces; also used for spirits) and a litre in the United States. 40 (US) 1.183 L: 40 US fl oz: 2.08 imp pt: 2.5 US liquid pints. Might have been inspired by the Canadian 40 imp fl oz bottle.
3. c. 24 (I) — Irish Act about grain measures decreed: unit of measure to be Henry VIII's gallon as confirmed by Elizabeth I; i.e. 272 + 1 ⁄ 4 cubic inches; standard measures of the barrel (32 gallons), half-barrel (16 gallons), bushel (8), peck (2), and gallon lodged in the Irish Exchequer; and copies were provided in every county, city ...
In the United States and Canada, large bottles are 22 U.S. fl oz (650.6 mL; 22.9 imp fl oz), or one-sixth of a US gallon (colloquially called a "bomber," a "deuce deuce," or "double deuce"). Some breweries also choose to use 500 mL (16.9 U.S. fl oz; 17.6 imp fl oz) bottles, often for smaller batches of beer.
In 1832, in the absence of any direction by Congress, the United States Treasury chose the second smallest gallon, the "Queen Anne gallon" of 231 cubic inches (3.785 litres), to be the official gallon in the United States for fiscal purposes. Sixteen US fluid ounces make a US pint (8 pints equals 1 gallon in both customary and imperial systems).
Most U.S. brewers sell beer in 1 ⁄ 2 barrels of 15.5 gallons, 1 ⁄ 4 barrels of 7.75 gallons, and 1 ⁄ 6 barrels of 5.17 gallons. Since keg sizes are not standardized, the keg cannot be used as a standard unit of measure for liquid volumes. Despite this, a number of people still refer to kegs as if they were a unit of measure.
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 ...
Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
Open channel flow describes cases where flowing liquid has a top surface open to the air; the cross-section of the flow is only determined by the shape of the channel on the lower side, and is variable depending on the depth of liquid in the channel. Techniques appropriate for a fixed cross-section of flow in a pipe are not useful in open channels.
