The wind pressure inside the tube is constant, while the pressure outside is not. Also, the pressure above and below the tube are constantly moving at the same rate, therefore same pressure. What happens if there are the same pressure? You get it? When pressure is the same on both sides, it stays in the air! The reason it falls is because it stopped spinning, and therefore the pressure is the same in all three places: Above, Inside, and Below. This is all a lie
What else can I help you with?
A tube contains enclosed air by a thread of mercury of 250 mm long when tube is horizontal the length of air is 250 mm long what is the pressure on the air column when atmospheric pressure is 750 mmhg?
A tube contains enclosed air by a thread of mercury of 250mm long when tube is horizontal the length of air is 250 mm long. The pressure on the air column when atmospheric pressure is 750 mm Hg is 3 Pascal or 3 N / m2.
What prevents mercury in the tube of a barometer from running out into the container at the bottom of the tube?
The top of a barometric tube is sealed leaving no place for air to escape. It works along the same principle as a drinking straw, but in reverse. In a drinking straw, the sucking motion reduces the pressure of the air inside the straw to a lower level than the air outside the straw. Liquid resists changes in volume due to pressure and is drawn up through the tube due to the air pressure exerted on the surface of the liquid outside the straw. In a barometric tube the tube is sealed at one end, trapping a finite amount of gas in the tube. The air pressure inside and outside the tube is equal, keeping the mercury suspended at a certain level. If the pressure outside is raised, more force is exerted on the surface of the mercury outside the tube than on the surface inside. This raises the level of the mercury in the tube until the pressure of the air is equalized -- there is still just as much air in the tube, but a smaller volume at a greater pressure.
What is the air tube called?
the largest test tube is beaker
How do glider use convection to stay flying?
Convection allows warmer air to rise because it is less dense than colder air. Because temperatures are greater near the ground (due to the ground's absorption of infrared radiation from the sun), the air at ground level tends to be warmer than the air at higher altitudes. Therefore, the air at ground level rises to form convection currents (currents of rising air), which, when impacting a glider's wings, generates lift, which allows them to remain in the air, or even rise to higher altitudes.
How well do air ionizers work?
Air ionizers use either a corona discharge tube or UV light to electrically charge air molecules. These charged molecules attract particles, cleaning and purifying the air.
Can birds stay still in the air while flying?
No, birds cannot stay completely still in the air while flying. They need to constantly flap their wings to maintain lift and stay airborne.
What is an example of air riddles?
I am the black child of a white father, a wingless bird, flying even to the clouds of heaven. I give birth to tears of mourning in pupils that meet me, even though there is no cause for grief, and at once on my birth I am dissolved into air. What am I? Smoke. Air Riddle
Do birds stay in the position they die in?
that depends if it was flying.... if it was flying and died it wouldn't stay in the air.... if it died at a slaughterhouse it wouldn't because it wouldn't die in a plastic bag.... hope it helped
Why while flying in an airplane you find your pilot pen start leaking?
Air pressure is forcing the ink out of the tube.
Why is it that one ear will not pop when flying or experiencing changes in air pressure?
When flying or experiencing changes in air pressure, one ear may not pop because the Eustachian tube in that ear is not able to equalize the pressure effectively.
Who invented the first flying airplane and how long did it stay in the air?
Orville wright and Wilbur Wrigt and stayed in the air for 12 seconds
Does mercury stay in the tube or escape into the air?
Mercury stays contained in the tube of a mercury thermometer when in use. It does not escape into the air as long as the thermometer is intact. However, if the thermometer is broken or improperly disposed of, mercury vapor can be released into the air, which is harmful to health.
Can aeroplane stay in the sky without movement?
Depends on what you compare it to. An airplane has to move in relation to the air to stay flying, but it doesn't really care about what the ground is doing. If it's windy enough you can point a slow-flying airplane into the wind and remain flying while not moving in relation to the ground.

What is the scientific explanation for how a bird can stay airborne while seemingly flying in place?
Birds are able to stay airborne while seemingly flying in place due to a phenomenon called "dynamic soaring." This involves the bird using the wind patterns and air currents to generate lift and maintain its position in the air without expending much energy. By skillfully maneuvering in these air currents, birds can effectively stay in one spot while in flight.
What is a vertical tube of air?
A vertical tube of spinning air is a mesocyclone.
