You are the engineer ischarge of an octane tank (3 ft diameter, 10 ft tall) and its safe purging. there is an incident with the tank and some of your engineer colleagues (who did not have an undergraduate safety class) are reporting that the tank exploded. the normal process pressure of the tank is 382 psig and ambient temperature of 298 k. initial reports are that the tank was not inerted properly causing it to explode. octane molecular weight - 114. [171] what is the available energy (lb tnt) in the tank using thermodynamic availability? [175] assuming an unconfined gas explosion, and that the tank contains octane gas, what is the available energy (lb tnt) in the tank if the octane exploded? [17c) after the incident investigation it was found that all tank fragments from the 'explosion were found less than 2000 ft from the tank. using your result from [17a). [17b) and fig. 6-26 what is your conclusion? i. e. was there an explosion?
