| System description | ||||||||||||||||||||||
| This virtual lab shows how an aerostatic balloon works. It is a nice example of application of the Archimedes' principle. The buoyant force of the aerostatic baloon is obtained by heating air inside its cavity. The buotant force is due to the difference of density between the hot air inside and the cold air outside the balloon cavity. The buoyant force compensate the balloon weigth (having into account the weight of the ballast and the people). | ||||||||||||||||||||||
