Contrails are created under certain atmospheric conditions and depends on the pressures and water vapor. They are created from wing tips or propeller tips and engine exhausts. Each airplane varies in their design of these features. Many modern airplanes have wings designed with supercritcal airfoils that produce more lift---and therefore developes a lower air pressure. Some jet fighters also have special designed wings and wing tips that will create contrails in a tight turn that earlier aircraft could not perform. Thus the F-18 can fly very low and still produce contrails. There are many factors that contribute to the contrails so there is no way to predict which aircraft will produce one.
Condensation Increases with relative HUMIDITY.
Because the amount of water vapour that the air can carry before condensation occurs varies with temperature. If you take hot humid air aind cool it down some of that humidity will drop out as condensation - turn into water.
No I just checked and mine has no condensation, thanks fro asking
Condensation polymerisation is when two molecules of the same substance (monomer) react together to form polymer chain (like polythene) and eliminate a smaller (usually water) molecule. For example, Nylon-6 is prepared by using condensation polymerisation of ε-Caprolactum
Lift can be increased by curving the wing downward. Most aircraft have 'flaps' at the rear inner edge of the wing to achieve this. Some aircraft even have 'slats' at the front of the wing to increase lift even more. - If you google 'aircraft slats', you will see a great picture of slats and flaps on an Airbus A310
Condensation trails or 'con trails'.
The trails behind an airplane are called contrails, short for "condensation trails," because they are formed by the condensation of water vapor in the aircraft's exhaust. When the hot, humid air from the engines mixes with the colder atmosphere at high altitudes, it creates ice crystals, resulting in visible streaks. These contrails can vary in appearance and duration, depending on atmospheric conditions.
Contrails or condensation trails
Contrails is a shortening of condensation trails.
The jet trails across the sky were caused by condensation. The condensation of the water on the outside of the glass left a ring on the table. The condensation fogged up his glasses when he walked into the house.
Contrails (short for "condensation trails") or vapour trails are artificial clouds that are the visible trails of condensed water vapour made by the exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets. If the air is cold enough, this trail will comprise tiny ice crystals.
Well, the jury is still out--literally, as one may join any of several class-action lawsuits on the matter--but elevated levels of aluminum, barium, and other metals in standing water does not bode well for the health of those being sprayed with these.
No, military jets are not the only aircraft that leave smoke trails behind. Both military and civilian jets can produce contrails, which are visible trails of condensed water vapor that occur when hot, humid air from the jet engine exhaust meets cooler temperatures at high altitudes. Additionally, some aircraft may intentionally release smoke for training or aerial display purposes. Therefore, smoke trails can be produced by various types of aircraft, not just military jets.
No. Chemtrails are a conspiracy theory which confuse the often-seen condensation trails - contrails - and combinations of this condensation with exhausts and other pollution with a more sinisterly intended chemical spraying. There is no way that "spraying" of this kind would cause any of the commonly claimed effects without telltale others.
The cloud created by a plane is called a contrail, short for "condensation trail." Contrails form when water vapor from the aircraft's exhaust cools and condenses into tiny ice crystals at high altitudes. These trails can dissipate quickly or persist and spread out, depending on atmospheric conditions.
The heat of the engines, especially jets, leaves a trail of white condensation in the cold atmosphere.
The white smoke often seen behind airplanes is typically condensation trails, or contrails, formed when hot, humid air from the aircraft's engines mixes with the colder atmosphere at high altitudes. This causes water vapor to condense into tiny ice crystals, creating visible trails. The intensity and persistence of these contrails can vary based on atmospheric conditions, such as temperature and humidity. In some cases, the smoke may also result from fuel combustion or engine malfunctions.
