Anonymous users2024-01-23The velocity of the air passing from the upper edge is faster than that of the lower edge (because the upper edge has a large arc and a longer arc length, which means that the distance is longer).
According to the Bernoulli equation of physics, the same fluid flowing through a certain surface has less pressure on the surface at a faster speed. Therefore, it is concluded that the atmospheric pressure on the upper surface of the wing is smaller than that on the lower surface, so that the lift force is generated, and the lift force reaches a certain level, and the aircraft can lift off the ground.
There is a formula that I don't know if you have ever seen: L Cl*1 2* *V*V*S.
Its significance is that the lift of an aircraft is the product of the following five quantities:
1.The lift coefficient Cl (that C represents the coefficient, l is the corner code, I don't have a character tool can not type), its value is related to many fine variables such as the windward angle of the aircraft, generally in a few tenths of a day, and the details are not very affectionate: (
2.One in two is.
3.Atmospheric density (the environment in which the aircraft is located, which can be high or low altitude).
4.The square V*V of the airplane's velocity relative to the surrounding atmosphere (it can only be expressed as this without a corner code).
5.Wing area S
This formula is only suitable for relatively slow flights, just like the common flight of large and small passenger aircraft, other aircraft (as long as the wings) can basically be used when the speed does not exceed Mach 1, but the high speed flight of Mach 2 or 3 like a fighter is not good, if the speed is too large, the air on the surface of the wing will become viscous, to take into account the Reynolds number, there is another formula at that time, it is very complicated, I don't understand. ：）
I work in a civil aviation company, so the answer should be relatively correct. Hope it helps. ：）
30-100, it is not recommended not to use, it is not environmentally friendly, and the service life is low.
Since each number of China Mobile users corresponds to the corresponding province, it belongs to the jurisdiction and service provided by the mobile company in each province. Therefore, you can directly call the 10086 human customer service in your area to inquire; Details of the cost of mobile toilets and answers to related questions.
The height of the glass partition is usually between meters, and then the high non-standard custom price is high, so it seems that the length of your sanitary partition is about meters, which is the rhythm of the bathroom as a bedroom, in view of this, it is necessary to be ready to be slaughtered, the glass thickness is at least 8 mm or more, and the area is too large It is recommended to install explosion-proof film to prevent tempered glass from exploding, so it seems that the price of a single square meter is calculated with aluminum alloy profiles How can it be more than 800 yuan, a full set of stone foundation, delivery and installation of 6000 yuan, If the stainless steel profile is selected, the price will go up.
I am the installation of the AIA integrated ceiling, plus the electrical appliances cost more than 5000, but I am the best heating dry and wet zonal heating system, if you install a single air heater I estimate that it will be less than 4000. But I think it's still worth it, after all, zonal heating is now the most popular bathroom heating, and heating is indeed better.
Moisture-proof board sanitary partition is actually very cheap, Jia Lifu pointed out that the moisture-proof board with ordinary plastic accessories, is 75 yuan square, if it is better stainless steel, nylon accessories, it is less than 110 yuan square.
