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.
Mobile homes, unless attached to lot by a foundation are considered personal property. Articles, that on their own would be considered personal property, once they are attached to land or a permanent part of a building and are then considered part of the real estate, are called fixtures. Examples of fixtures are built-in cabinets, installed lights, ceiling fans and plumbing.
