**PROBLEM**: A 120 gallon tank (26" diameter, 60" height) containing 40 Gallons of water is heated up until the tank ruptures from overpressure at 125 PSI (maximum tank rating). How to calculate the initial escaped steam velocity at the ruptured tank, assuming the gash is 2 feet long in the vertical direction? Also how to figure out the "wind speed" at 15 feet away?

**MY THOUGHTS**: We know at the time of rupture the tank is full of steam pressurized at 125 PSI, but there is a limited air and water molecules inside the tank, so this burst of steam can only travel a finite distance. What law of physics may govern this?
