1. Priciples of the Hot Air Balloon
... propane fuels. Propane is preferred over other hydrocarbons because its low boiling point allows a consistently higher vapor pressure for a given temperature, and is therefore a more efficient fuel. Hot air balloon is still used for recreation and scientific experiments, including Cosmic Microwave Background studies and astronomy. With the high number of uncertainties in steering balloons, it is crucial then ... Pressure in system (kg s^(-2) m^(-2) ) V=volume occupied by gas (m^3 ) n=number of moles of gas R=Universal Gas Constant (8.314 J K^(-1) mol^(-1) T=Absolute temperature of has (...
