WebA mixture of liquid fuels (propane 56%, acetylene 29%, methane 15%) is stored in room C. At a room temperature of 4 0 ∘ C, the vapour pressure of the fuel mixture would be 200 mmHg. What is the lower flammability limit (LFL) of the mixture? Assume percentage of each liquid fuel in the mixture remains the same in vapour state. WebThe Lower explosive limit of Methane is 5% volume in air and the Upper explosive limit is 17% volume in air. Hence, when the volume percentage of methane in an environment falls between 5% to 17%, the environmental condition is highly hazardous. The range of 5% to 17% is the explosive range for methane gas.
