The area of ocean between US and Great Britain that was too far out to allow air cover from fighter aircraft
An open vertical gap or empty space that separates one water system from another water system from another The open gap protects the water system from contamination by backflow or backsiphonage ADVANCE\x 540
Vertical, unobstructed distance, between the flood level in a plumbing fixture and the lowest water supply inlet, such as the distance between the rim of the tub and the faucet
A clear vertical space between a water or drain line and the flood level of a receptacle to prevent back-flow or siphoning from the receptacle in the event of negative pressure or vacuum Most plumbing codes require the air gap to be at least twice the diameter of the water or drain line, with a minimum of 1-1/2 inches (3 8 cm) (See vacuum breaker or back-flow presenter )
Open vertical gap or empty space that separates drinking water supply to be protected from another water system in a treatment plant or other location The open gap protects the drinking water from contamination by backflow or backsiphonage
A physical separation between the free flowing end of a potable water supply line and the overflow rim of an open or non-pressurized receiving vessel
The space between magnetic poles or between rotating and stationary assemblies in a motor or generator
The space between magnetic poles or between rotating and stationary assembly's in a motor or generator
The distance between the edges of any two conductors See also spacing Back to Words List
In a permanent magnet alternator, the distance between the magnets and the laminates
A device to prevent water backflow to a potable water supply It is an unobstructed open space that separates an outlet of the potable water supply (for example, a faucet) from any potentially contaminated source, such as water in a sink or drain pipe
An air gap in the water supply system in the unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet supplying water to a tank, plumbing fixture or other device, and the flood level rim of the receptacle
the air space between two magnetically or electrically related components; for example, the space between the armature and poles in a motor
A means of cross-connection control which eliminates the physical link between a safe water supply and potentially unsafe water Air gap must equal to at least two times the effective diameter of the inlet
The clearance between the rotating rotor and the stationary winding on an open motor Known as a vapor gap in a hermetically sealed compressor motor
The unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet supplying water to a tank, plumbing fixture or other device and the flood level rim of the receptacle (2)
A clear vertical space between the end of the RO drainline and the flood level rim of the house sanitary drain system connection point
The distance required between the linear motor magnet channel and the linear motor moving coil assembly The desired air gap ranges from 030"- 080" depending upon motor type
A nonmagnetic section, whether air or material, in an otherwise closed magnetic circuit
A low permeability gap in the flux path of a magnetic circuit Often air, but inclusive of other materials such as paint, aluminum, etc
type of network security where a network is kept physically separate from other local networks and the Internet (Computers); the distance between the contact armature and the iron core which is magnetized (Mechanics); clearance
In the drainage system, the unobstructed vertical opening between the lowest opening of a waste line and the flood level of the device into which it empties Purpose is to prevent backflow contamination Back to alphabetical list
