More data massaging (so totally illegal),
\(v_{boom\,water}=3.4354*\cfrac{1000}{10}=343.54\,ms^{-1}\)
\(T_{water}=\cfrac{343.54^2*18.01528*10^{-3}}{3*8.3144}=85.24\,K\)
from the post "Water Bombed And Cryogenic Hydrogen" dated 8 Nov 2017. And
\(n_{ice}=3.8\)
So,
\(T_{boom}=85.24*3.8=323.91\,K\) or \(50\,^oC\)
And we have a featured product "55℃ Magic Water Cup Vacuum Flasks" that cools to \(55\,^oC\) AND heats up cold water to \(55\,^oC\) on "http://www.banyakdeal.com/index.php/fun-unique/item/1057-55-magic-water-cup-vacuum-flasks-stainless-steel-thermos-mug"
The problem is the assumption of free particles in kinetic theory for gases and so the need for \(n_{ice}\), a variable that accounts for water molecules clustering because of hydrogen bonding.
As \(n_{ice}\) changes with temperature and additives like salt that affect hydrogen bonding, \(T_{boom}\) varies, if it exist at all.
