The handle also allows crews to install barricade lights to increase visibility. The product makes up a $90 million industry in the United States. [3] Until the late 1980s, construction crews typically used 55-gallon steel drums to guide traffic through construction areas. They were painted orange and white and filled with sand or water to keep ...
A 200-litre drum (known as a 55-gallon drum in the United States and a 44-gallon drum in the United Kingdom and the rest of the world) is a cylindrical container with a nominal capacity of 200 litres (55 US or 44 imp gal). The exact capacity varies by manufacturer, purpose, or other factors.
Hydrostatic pressure level sensors are submersible or externally mounted pressure sensors suitable for measuring the level of corrosive liquids in deep tanks or water in reservoirs. Typically, fluid level is determined by the pressure at the bottom of the fluid containment (tank or reservoir); the pressure at the bottom, adjusted for the ...

Also, Trombe walls using water as a thermal mass collect and distribute heat to a space in the same way, but they transfer the heat through the wall components (tubes, bottles, barrels, drums, etc.) by convection rather than by conduction and the convection performance of the water walls differs according to their different heat capacities.

Earlier I suggested that "55-gallon drum" might just be a description, not a name, but since then I have discovered the two military specs referenced in the article. Since I now know that "55-gallon drum" is short-hand for a whole set of standardized dimensions, I view it as a name and believe it should be listed first even in an SI-first article.
Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
alarm-system component that transmits coded sensor and subscriber information to a monitoring center to be processed into address and alarm-type information. Extension ladder A 20–60-foot ladder with one or more movable sections that extend beyond a base section, generally using a halyard rope and pulley mechanism for lifting and locking cams ...
