A Boiler: The Explosive Potential of a Bo

Standard physics laws of temperature and pressure are used to measure the explosive potential of boilers and pressure vessels. New calculations show, for instance, that if liberated in a rupture, a 30-gallon hot-water tank at 90 psig (or 104.7 psia) has approximately 314,095 foot-pounds of energy to flash its water into steam at 332°F.
