A mixture of liquid fuels (methane 56%, ethane 29%, propane 15%) is stored in room C. At a room temperature of 40C, the vapour pressure of the fuel mixture would be 200mmHg. 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. Round answer to 2 decimal places. % What is the vapour pressure of the mixture at LFL? Round answer to 2 decimal places. mmHg
