2. A tank with 80 ft diameter and 35 ft tall contains crude oil that is maintained at a level of 25 ft. Upon performing a hazard analysis on the unit, it is considered that one potential accident scenario includes an 8-inch (inside diameter) pipe at the bottom of the tank that could shear off, leaving a hole of the same diameter, and allowing the crude oil to drain out. If a 30-minute emergency response is required to stop the leak, how much crude oil will be spilled? Assume the tank is at ground level, atmospheric pressure is 1 atm, temperature is 75F, the specific gravity of crude oil is 0.9, and that the tank is vented to the atmosphere
