Bunding, also called a bund wall, is a constructed retaining wall around storage "where potentially polluting substances are handled, processed or stored, for the purposes of containing any unintended escape of material from that area until such time as a remedial action can be taken."
Main electrical distribution room in a large building. The back of an antique electrical room, still operational at a US plant as of 2014. All conducting busbars are open and operators must be careful not to touch them. An electrical room is a technical room or space in a building dedicated to electrical equipment. Its size is usually ...
Cofferdam – Barrier allowing liquid to be pumped out of an enclosed area, a temporary water-excluding structure built in place, sometimes surrounding a working area as does an open caisson. Offshore geotechnical engineering – Sub-field of engineering concerned with human-made structures in the sea, for information on geotechnical ...
Penetrants, or penetrating items, are the mechanical, electrical or structural items that pass through an opening in a wall or floor, such as pipes, electrical conduits, ducting, electrical cables and cable trays, or structural steel beams and columns. When these items pierce a wall or floor assembly, they create a space between the penetrant ...
For experimental characterization, a distinction must be made between contact resistance evaluation in two-electrode systems (for example, diodes) and three-electrode systems (for example, transistors). In two-electrode systems, specific contact resistivity is experimentally defined as the slope of the I–V curve at V = 0:
Mechanical room in a large office building. Mechanical room in federal building, Los Angeles, California. A mechanical room, [1] boiler room [2] or plant room [3] is a technical room or space in a building dedicated to the mechanical equipment and its associated electrical equipment, as opposed to rooms intended for human occupancy or storage.
In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid is the kinetic energy associated with the speed of flow of the fluid, plus energy from static pressure in the fluid, plus energy from the height of the fluid relative to an ...
In sailing and boating, a vessel's freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. [1] In commercial vessels, the latter criterion measured relative to the ship's load line , regardless of deck arrangements, is the mandated and regulated meaning.
