Mixtures of dispersed combustible materials (such as gaseous or vaporised fuels, and some dusts) and oxygen in the air will burn only if the fuel concentration lies within well-defined lower and upper bounds determined experimentally, referred to as flammability limits or explosive limits. Combustion can range in violence from deflagration through detonation. Limits vary with temperature and pressure, but are normally expressed in terms of volume perc… WebIn gas-detection systems, the amount of gas present is specified as a percentage (%) of LEL. Zero percent Lower Explosive Limit (0% LEL) denotes a combustible gas-free …

The explosive flammable range of a combustible gas or vapor is the range between the lower exposure limit (LEL) and the upper exposure limit (UEL) for that particular gas or vapor. This is the flammable range at which the gas will burn. nasa tech day on the hill

In addition, because of its specific gravity (0.60), which is lower than that of air (1.00), natural gas rises if escaping, and thus dissipates from ... nasa teacher summer program
