What advantages did airplanes provide in the war?
Airplanes help nations attack from the air. Airplanes give nations a strategic advantage because they can do a lot of damage from the air.
Is compressed air more buoyant than atmospheric air?
Since weight is the measure of an object's gravitational pull, the compressed air does not weigh more. The difference is in the density of the air. A tank filled with compressed air will weigh more than a tank that is filled with air at normal atmospheric pressure.
How submarines float on water?
The air trapped in the hull (this includes the buoyancy tanks) make it lighter than the water it displaces. The buoyancy tanks surround the main hull (where the people and machinery are), and can be flooded to allow the ship to sink. Refilling them with air (from compressed air tanks) allows it to return to the surface.
Why many lifesaving buoyancy aids contain air?
Buoyancy aids contain air because it is a lightweight, readily available, and effective way to provide flotation. The air inside the buoyancy aid increases its volume while reducing its weight, helping the user stay afloat in water. Additionally, air is relatively inexpensive and does not add unnecessary bulk or weight to the buoyancy aid.
Why do submarines submerge?
To control its buoyancy, the submarine has ballast tanksand auxiliary, or trim tanks, that can be alternately filled with water or air. When you fill it with water, it sinks, When you first let the water out then you let the air in (from compressed air in the submarine) it floats.
How does a submarine floats then sinks then floats?
It is a matter of buoyancy. There are large tanks that can be filled with sea water or with air. To submerge they pump the air into compressed tanks and the water fills it up sinking the sub. When they want to go back up, they blow the water out using the compressed air.
HOW can a submarine float in water sink in the sea or come up to the surface?
The buoyancy of a submarine may be varied by having ballast tanks, into which either water or compressed air may be added or subtracted to vary the average density of the boat. Thus it will have a variable buoyancy.
What does air density determine?
Air density determines how much mass is present in a given volume of air. It affects things like buoyancy, pressure, and the ability of objects to move through the air, such as airplanes and birds. Changes in air density can impact weather patterns and climate.
Which categories is usage of compressed air and gas divided into?
The three major categories of usage for compressed air and gas are: compressed air and gas for process services, compressed air for power, and compressed air for general industrial applications.
Does airplanes sometimes stop in air?
NO, airplanes have to keep moving in the air.
How is compressed air used in designs?
Compressed air is often used in designs for pneumatic systems, such as in tools and equipment that require air pressure to function. It is also used for air brakes in vehicles, HVAC systems, and spray painting applications. Compressed air can provide a reliable and versatile power source for various industrial and commercial design applications.
What do compressed air dryers do?
A compressed air dryer is a device for removing water vapor from compressed air. Compressed air dryers are commonly found in a wide range of industrial and commercial facilities.
