A vertical tube of spinning air is a mesocyclone.
A vertical tube of spinning air is called a vortex. Vortices can occur naturally in the atmosphere, such as tornadoes or dust devils, or they can be created artificially in various engineering applications.
The vertical portion of the fermentation tube allows gases produced during fermentation to escape without letting air in. This helps prevent oxygen from entering the fermentation vessel, which could negatively impact the fermentation process.
It depends on the weapon (torpedo, missile, mine, or vertical launched missile) but the 2 primary methods are water impulse ejection (torpedoes, torpedo tube launched missiles, mines) and air ejection (vertical launched missiles). Torpedoes also have the ability to swim out (engine startup in the tube) from the torpedo tube if the impulse ejection system is down.The water impulse system is pretty simple; the tube at the breach end is connected via another vertical tube to a water reservoir that has a piston ram. When high pressure air is dumped from a flask directly into the air side of the piston, it instantly moves the piston ram, forcing the water on the other side of it out of the open tube, ejecting the weapon along with it.For vertical launched weapons, it's simply a high pressure air bubble that ejects the missile; the rocket motor doesn't actually fire until the weapon clears the ocean surface.

Air flowing quickly over the open top of a vertical tube lowers the air pressure in it. This causes liquid in the tube to rise. (It rises due to the higher pressure acting on the other end. The tube is marked to indicate the wind speed. Alternatively, if the open vertical tube is in still air and it is connected at its lower end with a horizontal tube containing a flowing liquid, the liquid in the vertical tube will fall when the horizontal flow past the lower end increases.
A simple vertical boiler is a type of fire-tube or water-tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation.
The level holds a tube of oil with 2 marks set 5millemetres apart at its centre. a bubble of air will travel along the tube in the opposite direction to the angle the level is held at. When the bubble sits between the 2 lines it indicated that level is either horizontal or if the tube is set so it can indicate a vertical then it shows that the level is vertical . Used by builders in the main it helps them ensure that items are true vertical ( a wall for instance) or true horizontal (a kitchen work top for instance)
the vertical accelaration in case of a projectile is 'g'.

there are two types of boilers water tube and fire tube. fire tube boilers are divided in to two categories vertical and horizontal. this according to the construction of fire tubes. it is said that vertical boilers are inefficient than horizontal boilers. The vertical boiler is small capacity, and horizontal boiler is higher capacity, well, the horizontal boiler have many types according the drums, there are single drums boiler, and double drums boiler, while, the single drums boiler have fire tube boiler and water and fire tube boiler, double drums boiler is usually water tube boiler.
