Balloon a wide range of applications. The rubber balloon was invented by Michael Faraday in 1824, during experiments with various gases. Balloon decorating Balloons are used for decorating birthday parties, weddings, corporate functions, school events, and for other festive gatherings. The artists who use the round balloons to build are called "stackers" and the artists who use pencil balloons to build are called "twisters." Most commonly associated with helium balloon decor, more recently balloon decorators have been moving towards the creation of air-filled balloon decorations due to the non-renewable natural resource of helium limited in supply. The most common types of
Solar balloon a little over 6 seconds. Below is the energy balance equation of the rate of energy lost of a solar balloon when drawing the boundary line around the balloon. The Solar Balloon experiences heat transfer due to convection and heat transfer due to radiation. Ėout= tσπr(TS4-TF4) + hπr(TS-TF) Tds=du+PdV Δs = ∫(cv/T)dT + Rgasln(V2/V1) Δs = cvln(T2/T1) The system is in equilibrium when the energy lost from the balloon through convection, radiation and conduction, equals the energy received through radiation from the sun. In 1972, Dominic Michaelis, a British architect and the inventor of many solar utilities and projects, invented
