A tank of chlorine contains \(1000 \mathrm{~kg}\) of chlorine at 50 -bar gauge. What is the maximum hole diameter (in \(\mathrm{mm}\) ) in this tank that will result in a downwind concentration equal to the ERPG-1 at a downwind distance of \(300 \mathrm{~m}\) ? Assume \(1 \mathrm{~atm}, 25^{\circ} \mathrm{C}\), a molecular weight of chlorine of 70.9 , and that all the liquid chlorine vaporizes.
