by Eq. 6.18. As a result an amount of energy -dE, equal to 
47 R Vole Lis aR is dissipated and remains bound in the 
water after the passage of the shock wave and return of the pressure 
to the value zero. The rate of dissipation is therefore given by

which agrees exactly with Eq. 6.16 obtained from our theory of 
propagation. 
Since all the quantities Py? 8, I) and Ep depend upon 
the explosive producing the wave only through the parameter 4E , 
it is desirable to summarize the formulas relating them to this 
parameter, cf. Eqs. 6.3, 6.9, 612, and 6.15.
