A spray nozzle or atomizer is a device that facilitates the dispersion of a liquid by the formation of a spray. The production of a spray requires the fragmentation of liquid structures, such as liquid sheets or ligaments, into droplets, often by using kinetic energy to overcome the cost of creating additional surface area.
In fire protection engineering, the K-factor formula is used to calculate the volumetric flow rate from a nozzle. Spray nozzles can for example be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.
A common form of knock-down is a complete knock-down (CKD), which is a kit of entirely unassembled parts of a product.It is also a method of supplying parts to a market, particularly in shipping to foreign nations, and serves as a way of counting or pricing. [1]
A crosshead as part of a reciprocating piston and slider-crank linkage mechanism. Cylindrical trunk guide Hudswell Clarke Nunlow; crosshead and two slide bars. In mechanical engineering, a crosshead [1] is a mechanical joint used as part of the slider-crank linkages of long stroke reciprocating engines (either internal combustion or steam) and reciprocating compressors [2] to eliminate ...
Also known as the Walerga Assembly Center, it was one of the smaller WCCA camps and operated for 52 days, from May 6 to June 26, 1942. [2] Upon closure of the assembly center, the site was turned over to the Army Signal Corps and dedicated as Camp Kohler Training Camp. Camp Kohler also served as the Walegra Engineer Depot during the war. At the ...
In sidevalve engines the head is a simple plate of metal containing the spark plugs and possibly heat dissipation fins. In more modern overhead valve and overhead camshaft engines, the head is a more complicated metal block that also contains the inlet and exhaust passages, and often coolant passages , Valvetrain components, and fuel injectors .
As "perhaps the most complex of all the structures on the vehicle", the B-pillar may be a multi-layered assembly of various lengths and strengths. [11] B-pillars also exist as integral elements of an automobile unibody on two-door sedans and hatchbacks, separating the front door from either fixed or movable glass of the second row of seating.
