Consider a 5,000 gallon hot water tank which has a working pressure of 0.5MPa.?

As a result of some malfunction, the pressure in the tank rises to 2 MPa at which point the tank explodes. Taking the atmospheric pressure to be 100 kPa and uming the liquid in the tank to be saturated at the time of the explosion, determine the total explosive energy of the tank in terms of TNT equivalence. (The explosive energy of TNT is about 3250kJ/kg, and 5kg of TNT can cause total destruction of unreinforced structures within about a 7-m radius
