A flow of air in a loop is commonly known as a "closed-loop air circulation system." This system involves air being circulated continuously within a defined loop or circuit to facilitate cooling, heating, or ventilation within a specific area or system without any external exposure. Closed-loop systems are often found in HVAC systems and industrial applications to maintain air quality and temperature control efficiently.
The flow of air is caused by coastal winds. The hot air rises, and colder air blows in to take its place. (land breeze)
Erosion typically occurs on the outer bank of a meander loop due to increased flow velocity and shear stress along the bend. As the water flows along the outer bank, it exerts erosional forces, causing the bank to erode and the meander loop to migrate downstream over time.
Air is considered to be a fluid because it can flow and conform to the shape of its container, similar to liquids. This property is a characteristic of fluids, which include both gases and liquids.
An air flow meter measures the amount of air entering an engine to help determine the appropriate fuel-to-air ratio for combustion. This helps optimize engine performance and fuel efficiency by ensuring the correct amount of fuel is injected based on the amount of air being drawn into the engine.
Air flow is initiated when there is a difference in air pressure between two points. Air moves from areas of high pressure to areas of low pressure to equalize the pressure. This can be caused by various factors such as temperature gradients, fans, wind, or the movement of objects through the air.
It is called a convection.
It's called wind.
This flow of air is called convection, where warmer air rises and cooler air sinks, creating a continuous loop of circulation. This process occurs due to the difference in density caused by variations in temperature and pressure.

The air flow meter in a car tells the engine management computer how much air the cars engine is using. This is important because the fuel to air ratio must be maintained for proper combustion of the fuel. If there is too little fuel for the amount of air, the engine will tend to stutter misfire and accelerate poorly. If there is too much fuel for the amount of air, the engine will smoke, have poor efficiency , high emissions, and also have poor performance. When the computer in in "closed loop" operation, it calculates how much fuel to deliver based on the measurement received from the air flow meter. The computer is smart and many can calculate what the air flow is supposed to be without the air flow meter being hooked up. The engine rpm, manifold pressure and temperature can be used to get a very close estimate of the air flow at the lower engine rpm range. Sometimes the computer operates in "open loop" and does such calculation. Open loop takes place in some cars when the car just starts and is warming up, or if there is a problem with some part of the system, so you can still operate the vehicle. The oxygen sensor on a car is also used while in the closed loop mode to assist in determining how much fuel to inject. The injectors control the fuel by opening and closing very fast, the longer the injector is open, the more fuel. Fuel pressure upstream of the injector is held constant, in that way the fuel delivered is directly proportion to the amount of time that the injector is open.
An air flow is any flow of air, particularly the motion of air around a moving aircraft or aerofoil.
