The phrase "air weight" is not commonly used in written English and may cause confusion.
It could be used in contexts discussing the weight of an object in air, but it is not a standard term.
Example: "The air weight of the balloon was significantly less than its weight in water."
Alternatives: "weight in air" or "weight under air conditions".
These forces are lift, an upward-acting force; drag, a retarding force of the resistance to lift and to the friction of the aircraft moving through the air; weight, the downward effect that gravity has on the aircraft; and thrust, the forward-acting force provided by the propulsion system (or, in the case of unpowered aircraft, by using gravity to translate altitude into speed).
The fact that the balloon rises as it loses weight might be obvious, but it is important to realise that it is the manipulation of the balloon air weight which governs the rising and falling of the balloon.
Back then, the Jets played at Shea Stadium and worked out in an open-air weight room that resembled a garage.
One mortar round exploded by the open-air weight room, nearly killing a marine captain and a photographer for The New York Times, who crouched together against a stone wall about 15 feet away.
Dive packages include three single-tank boat dives daily; two single-tank night dives; and the use of air tanks, weight belts and weights.
In second position en l'air ("in the air"), the weight is supported by one foot while the other is raised at the side.
The vapour pressure would be 17 mb (0.02 standard atmosphere) and the mixing ratio about 11 parts per thousand (11 grams of water per kilogram of air by weight).
The percentage yield was expressed in terms of air dried weight of plant material.
So in presence of air the weight taken in an electronic balance varies remarkably for the same sample.
The substrates were allowed to dry in the sun for 10 days and regularly (daily) weighed for five consecutive days to determine the change in the air dry weight of substrates.
