What is a air gap?
An air gap, as it relates to the plumbing trade, is the unobstructed verticalspace between the water outlet and the flood level of a fixture.
A simple example is the space between a wall mounted faucet and the sink rim (this space is the air gap). Water can easily flow from the faucet into the sink, but there is no way that water can flow from the sink into the faucet without modifying the system. This arrangement will prevent any contaminants in the sink from flowing into the potable water system by siphonageand is the least expensive form of backflow prevention.
A common use of the term "air gap" in home plumbing refers to a fixture that provides back-flow prevention for an installed dishwasher. This "air gap" is seen above the countertop as a small cylindrical fixture mounted parallel with the faucet. Below the countertop, the drain pipe of the dishwasher feeds the "top" of the air gap, and the "bottom" of the air gap is plumbed into the sink drain below the basket. When installed and maintained properly, the air gap works as described above, and prevents drain water from the sink from backing up into the dishwasher, possibly contaminating dishes. Water flowing from the fixture into the sink indicates a need for maintenance or repair.
To further illustrate the air gap, consider what could happen if the air gap were eliminated by attaching a hose to the faucet and lowering the hose into a sink full of contaminated water. Under the right conditions (if the water supply loses pressure and the sink is higher than the point at which the water supply enters the house, for instance), the dirty water in the sink will be siphoned into the water pipes through the hose and faucet. The dirty water then will be dispersed throughout the drinking water system.
All plumbing codes require backflow prevention in several ways. The plumbing fixture manufacturers build the fixtures to meet these codes. A plumber must not build cross-connections in his daily work practices, and Plumbing Inspectors look for improper designs or connections of piping and plumbing fixtures. A common misconception is that a "high loop" (routing a drain line above a sink's flood level, for instance) will provide the same function as an air gap; this is not true, because the continuous
The resistance of an air gap is effectively infinite until it reaches its arcover threshold voltage; then it drops to near zero as the air in the gap ionizes. It returns to effectively infinite when the current through the gap is insufficient to keep the air ionized.
Your air gap is not supposed to leak. Check the hose that leads from the air gap to the garbage disposal for a clog. This should resolve your problem.
Water is non-compressible. The air gap is what allows additional air to be pumped into the rocket.
Yes and an air gap for a basin faucet and an air gap located in most dishwasher and washing machines. The actual size of the air gap is 2 times the effective opening (supply pipe) but in no case less then 1 "
It is important to have the air gap in a magnetic circuit so that everything works properly. The air gap allows magnetic flux flow to the main source; without it, it would not work properly.
Specific magnetic loading is ratio average flux air gap and flux path of air gap:
The used to have SF6 in the air gap.
The air gap is the distance between the module (armature) and the magnets of the flywheel. Generally 0.010" or so
Increasing the air gap will significantly increase its leakage reactance, thereby increasing its no-load current.
Lesser air gap, less is the magnetising current (which is lagging reactive component of current)causing better p.f.
A section of air is heated by the sun, causing that air to rise. Cold air close to the ground rushes in to fill the gap that the rising air left. The warm air begins to cool as it gains altitude and begins to fall back down, while the cool air that rushed in to fill the gap begins to warm and rise. The cooled warm air falls into place with the air that is… Read More

The correct air gap is .032 in.
The listed air gap for this engine is .030 in.
Would loss of heat be reduced or increased by increasing the air gap between the double paned windows than the usual necessary gap?
Because air is such a poor conductor of heat compared to glass (it is much less dense) increasing the air gap will further reduce the rate of heat transfer.
The air gap between frictional surfaces of the clutch plate and clutch rotor should be 0.40-0.50mm (0.015-0.020").
An air-gap is a device you connect the dishwasher to. It is mounted on top of the sink to prevent back-flow of water from the sink or garbage disposal into the dishwasher.
Tecumseh website, "All spark plugs air gap is .030."
All motors (and, indeed, generators) have a very narrow air gap. This is because the air gap forms part of the machine's magnetic circuit. A 'magnetic circuit' is the path in which the magnetic field produced by the machine's field windings is constrained, and is made up of silicon-steel in series with a very narrow air gap. Air has a very much higher reluctance (equivalent to resistance in an electric circuit) than the silicon-steel part… Read More
I am not 100% sure, but I do not believe the air gap can be adjusted on that compressor. Manufacturers use washers/ shims to set the air gap, and to adjust it, you would need to pull off the hub and check the shims (start with pulling only one off).
The point gap for all air cooled VW engines is .016" (inch).
Air gap between coil module and flywheel should be .010 inches.
Tecumseh provides dealers with a 0.012" air gap guage, but 0.010 - 0.014" will do.
All modern vehicles have a gap above the fuel level when full for safety reasons.
No, you don't.
What is the air gap for a Nippondenso 10p AC compressor and the recommended torque for the mounting bolts?
The air gap is .016 - .030 compressor to engine 36 ft lbs compressor to bracket 16 ft lbs
in rotating machines the air gap permeance in front of the slots changes with rotating rotor that it change flux in air gap and affect the voltage and current in machine. baradaran from jondishapour university iran
Mainly air gap is necessary in magnetic circuit for two necessary reasons: 1. to prevent saturation 2. to allow an object to move in the magnetic field
ventilation: air in from under the door, air out through the vent in the ceiling
Basically useful fluke is the flux that flows with in the magnetic circuit of an armature. That is why when there is an air gap the flux enters the armature which makes it useful flux! Hope that answers your question!

The gap should be about .0125 in. (.3175 mm.) or the thickness of heavy paper.
the land heats up,heating the air, Hot air rises, cold air from the sea rushes in to fill the gap....repeat
.016 - .021 point gap. .033-.038 spark plug gap. Click the link for all the info you will ever need on the 1957 Chevy.
The gap should be between .006 and .010 if it has aluminum clylinders. The gap should be between .010 and .014 if it has cast iron cylinders.
Use an insulator ... such as an air gap, or asbestos.
To provide a place for the spark to happen.
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
The required spark plug air gap for the 83 model, 15 hp Johnson is .030 in.
Prior to installation; using a feeler guage check the clearence between the armature assemble and rotor at 3 evenly spaced locations. There should be a gap of .060 and .125 (1/8 inch. if the gap is exceeded the armature and rotor should be replaced. With the clutch disengaged, using a feeler guage check the clearence (Air Gap) at both access slots between the ears of the brake flang. This must be between .010 and .015… Read More
If you have fuel and air and want it to burn, then you will need a source of fire. By having a positive and ground you will have to have a gap for the electricity to jump. That will create a spark and it will create combustion.

The magneto air gap is a precision measurement that's taken between the edge of the flywheel and the ignition coil armature. The flywheel and the crankshaft are held together in alignment by the flywheel key.
The gap is 0.30. It is on the owners manual ? 10-28-08 That sounds like a spark plug gap. Other specs: Armature air gap: .008-.012 Valve/tappet: .004-.006 intake AND exhaust, cold.
Did you happen to replace the disposal prior to this? A common mistake is forgetting to knock out the plug on the disposal, where the hose attaches, stick a screwdriver inside and beat it with a hammer to knock it out.
It is not an easy answer to explain. As warm air touches cold air, it rises, and the cooler air quickly fills the gap caused by the rising warm air. this mass movement of air is the wind... Corrections if i am wrong please.
