Sectional coolers consist of a rotating cylinder ("drum" or "shell"), a drive unit and a support structure. At each end of the drum there are stationary chutes for material feed and outlet. Depending on the size of the cooler the drum is pivoted on a shaft running through its axis, or is supported on running treads or external ring gears.
A similar object, the Burton Agnes drum was found 15 miles away near Burton Agnes in 2015, [2] and another example, the Lavant drum, was excavated in 1993 in Lavant, West Sussex. [3] Their purpose remains obscure. They were given the name "drum" to describe their shape, rather than from any thought they might be percussion instruments.
An air-cooled engine uses all of this difference. In contrast, a liquid-cooled engine might dump heat from the engine to a liquid, heating the liquid to 135 °C (water's standard boiling point of 100 °C can be exceeded as the cooling system is both pressurised, and uses a mixture with antifreeze) which is then cooled with 20 °C air.
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.
The drum of the Hippo water roller is made from UV-stabilized linear low-density polyethylene and is designed to cope with the rough surfaces found in rural areas. The drum's volume is 90 litres (24 US gal). [2] It has a large, 135-millimetre (5.3 in) diameter opening for easy filling and cleaning. [3]

Chalk paint may be applied with a brush, roller, or spray gun. [5] The paint should be applied in thin layers and will typically dry within two hours. [3] A topcoat sealer, such as wax or lacquer, should be applied to avoid the flaking of the chalk paint. The topcoats may enhance the decorative characteristics. [1] [2] [3]
