What is the size of a barrage balloon?
A barrage balloon typically has a diameter of around 55 feet and a length of about 72 feet.
Who built the first barrage balloon?
The first barrage balloon was built by British engineer Sir Barnes Wallis in 1912. It was designed to defend against aircraft attacks during World War I by creating obstacles in the sky for enemy planes.
What happens to the hot air balloon when it reaches an altitude of 10000 meters?
the air pressure outside of the balloon decreases.
How does the altitude effect the size of a balloon?
As the external pressure drops with increasing altitude, balloons generally expand with height.
Why does a helium-filled balloon rise to a certain altitude in the atmosphere and float there instead of rising further?
The helium-filled balloon rises to a certain altitude in the atmosphere and floats because at that point, the buoyancy force (upward force) of the helium inside the balloon equals the gravitational force pulling the balloon downward, resulting in equilibrium. This balance of forces causes the balloon to stay at a stable altitude instead of rising further. Additionally, the surrounding air pressure and density decrease with altitude, affecting the balloon's ability to rise further.

What colour is a barrage balloon?
it is blue with green spots
What U.S. companies built barrage balloons in World War 2?
the barrage balloon company.went bust in 1946
What is a barrage balloon?
A barrage balloon is a large helium-filled balloon that is tethered to the ground with steel cables. It is used as a defensive measure to deter low-flying aircraft from attacking ground targets. The cables are intended to damage or destroy the aircraft if they come into contact with them.
What was the barrage kite used for?
The barrage balloon was used in WW2 in an attempt - not very successful - to protect parts of Britain from enemy bombers.
Would there be more air pressure in a balloon at sea level or high in the sky?
provided the balloon has not reached its elastic limit (it has burst!), the air pressure inside and outside will essentially be equal. [The pressure inside will be slightly less, which is where the lift comes from.] But even at altitude, the pressure will be approximately equal in and out, for at altitude, the balloon will have swelled, thus reducing the internal pressure. It will eventually reach an altitude at which the internal pressure and the external pressure will be equal, and the balloon will have reached maximum expansion. Filled at sea level, a balloon will seem empty and floppy, and very tall and thin. At altitude the balloon will fill out as the external pressure reduces.
What might cause a balloon blown up at low altitude to burst if it is taken to a higher altitude?
at altitude the balloon's external air pressure has been greatly reduced, often expanding the balloon to the bursting point.

Why is there a maximum altitude for aircraft?
After the maximum altitude is reached the preesure is so much that the pilot cant go farther. If he goes more than the maximum altitude he will lose consiousness.
What measures cloud altitude and direction?
a weather balloon
Why was the barrage balloon so big?
its cables kept attack planes from flying in low to make accurate attacks.
What is something they had in World War 2 and is two words starting with B and B?
Buzz bomb or barrage balloon.
