The female part of the connector is the 7×7× 4 + 1 ⁄ 2 in (180×180×110 mm) corner casting, which forms each of the eight corners, welded to the container itself, and has no moving parts, only an oval hole in the tops of the four upper corners, and in the bottom of the four lower corners.
The two 20‑foot containers at the bottom are rigidly joined with four twistlocks between them, so that they could also be placed higher in the stack. Note: 48-foot and 53-foot units can only be stacked in a 40-foot compliant stack if they are just 8 feet wide, or have special structural provisions to handle their usual 6 inch (15.2 cm) extra ...
Liquid water and ice, for example, form a frigorific mixture at 0 °C or 32 °F. This mixture was once used to define 0 °C. That temperature is now defined as the triple point of Water with well-defined isotope ratios. A mixture of ammonium chloride, water, and ice form a
A container chassis, also called intermodal chassis or skeletal trailer, is a type of semi-trailer designed to securely carry an intermodal container. Chassis are used by truckers to deliver containers between ports, railyards, container depots, and shipper facilities, [1]: 2–3 and are thus a key part of the intermodal supply chain.

A set of communicating vessels Animation showing the filling of communicating vessels. Communicating vessels or communicating vases [1] are a set of containers containing a homogeneous fluid and connected sufficiently far below the top of the liquid: when the liquid settles, it balances out to the same level in all of the containers regardless of the shape and volume of the containers.
Suction is the vertical distance between the fluid to be pumped and the centre of the pump, while lift is the vertical distance between the pump and the delivery point. [4] The depth from which a hand pump will suck is limited by atmospheric pressure to an operating depth of less than 7 meters. [ 5 ]
