Convergent nozzles accelerate subsonic fluids. If the nozzle pressure ratio is high enough, then the flow will reach sonic velocity at the narrowest point (i.e. the nozzle throat). In this situation, the nozzle is said to be choked. Increasing the nozzle pressure ratio further will not increase the throat Mach number above one.
Furniture, Fixtures and Equipment. The furniture, fixtures and equipment fixed asset category usually has a lower capitalization threshold than other fixed assets due to their lower acquisition costs. Desks, chairs, tables, couches, filing cabinets and movable partitions are part of your furniture fixed assets. Fixtures are anything attached to your building or structure that, if removed, would cause damage. Common fixed asset fixtures are installed lighting, sinks, faucets and rugs. Your copy machines, telephones, fax machines and postage meters are included as office equipment fixed assets.
A light fixture (US English), light fitting (UK English), or luminaire is an electrical device used to create artificial light by use of an electric lamp. All light fixtures have a fixture body and a light socket to hold the lamp and allow for its replacement. Fixtures may also have a switch to control the light. Fixtures require an electrical connection to a power source; permanent lighting may be directly wired, and moveable lamps have a plug.
