Misconceptions about Air - Chemistry Land

Oct 1, 2007 . Misconception #3: Suction. Suction Cups. The way suction cups work is usually very much misunderstood. Contrary to popular believe, suction is not what holds suction cups to the surface. Before a suction cup even attaches to a surface, there is air pressure pushing on the surface at about 15 pounds per.

Bad Physics. Misconceptions spread by K-6 Grade School Textbooks

But we also know that hot air is less dense that cool air of the same pressure, so hot must rise through cooler air. Mix the two ideas together: dense air which is full of water droplets becomes less dense when heated, and at a certain higher temperature it should be buoyed upwards by the atmosphere even though it's still full.

The myths around food-grade compressed air - Food Processing

Compressed Air Efficiency | Busting compressed air myths .

Feb 6, 2012 . Heatless dryers often can be equipped with vacuum-assist purge air (Figure 3) to reduce purge air regeneration to a nominal 3 psia, which increases the expansion ratio to 2.6%, or 2.6 scf of air. At atmospheric pressure, 2.6 scf can hold the same amount of moisture as 100 scf of compressed air at 100 psig.

List of common misconceptions - Wikipedia

The paper rises because the air follows the curve of the paper and a curved streamline will develop pressure differences perpendicular to the airflow. Bernoulli's principle predicts that the decrease in pressure is associated with an increase in speed, i.e. that as the air passes over the paper it speeds up and moves faster.

10 Airplane Myths Debunked - Business Insider

Sep 24, 2013 . Discovery's "Mythbusters" took this one on, and found it categorically false. But because planes are not pressurized to sea level (it's the equivalent of breathing at about 8,000 feet up), there's less oxygen in the air, which can make you feel drunk. For the sake of comfort, it is still a better idea to stand when.

Cambridge scientist debunks flying myth - Telegraph

Jan 24, 2012 . Scientists have debunked one of the most commonly held myths in science - why aircraft fly. . Aeroplanes can fly because their wings cause the air pressure underneath to be greater than that above, lifting them into the air. But engineers have for years been frustrated by a theory which wrongly explains.
