Get A Hot Air Balloon Rose From A Height Of 100 2020-2024

The highest that most hot air balloons are allowed to rise today is 3,000 feet, but even though that is standard procedure, there are those that want to see what a balloon could be capable of if it were allowed to reach its maximum potential.

Since the internal pressure of a hot-air balloon is the same as the outside ambient pressure we let Pi=Po=P. Likewise, the volume of displaced air outside of the balloon equals the vol- ume of the hot air inside the balloon so, Vi=Vo=V.

A typical balloon is about 55 feet across and 60 to 80 feet tall. They are categorized by how much air the envelope can contain. a common sizes is the AX-7, with an envelope volume of 77,000 cubic feet. This is the most widely flown model because it can be easily handled by a crew of three to four people.

The envelope is laid out on the ground before a flight and partially inflated with cold air from high-powered fans before the air is heated with the burners to create lift required. Passenger-carrying balloons range in size from those holding 77,000 cubic feet of air (called a '77') to 600,000 cubic ft (a '600').

Hot air rises because of gravity and the dependence of air density on temperature – hot air is less dense than cold air at the same pressure. Hot air responds to the buoyant force and floats upwards, Archimedes principle in action.

This could very well be the case down on the ground but remember that a hot air balloon travels at anything up to 5,000 feet in the air. Both wind direction and strength can differ the higher you go.

That's twice as high as most airliners fly at, and appreciably higher than almost all but the most specialised military jets. What do high altitude balloons carry?
