6. Benzene is stored inside a storage area, 10ft long and 10ft wide with an 8 -ft ceiling. This storage area has a ventilation system that changes the air in the room six times per hour. The storage area is also equipped with a flammable vapor detector that sounds an alarm when the flammable vapor concentration reaches 25% of the LFL for benzene. What is the minimum benzene spill rate, in lb/hr, that will set off the flammable vapor alarm in the room? Assume a pressure of 1atm and a temperature of 80F[10%]
