7.6 Calculate the minimum amount of combustible liquid (Table 8) that must evaporate in a closed room with volume Vp under normal conditions in order to create an explosive concentration of combustible vapors. It is conditional to accept that the vapors of a combustible liquid are evenly distributed in the volume of the room. Calculate the lower concentration limit of flame propagation from the limiting calorific value.
