         D" from  experiment, one can construct the dependence Q(  We)  for  the given rock
         based on (10.30).
            The relations Q/Qo(we/(E"Qo)), 1/Je(we/(E"Qo)) = (Q- Qo)E" /we  for some
         media  are  presented  in  fig.  65.  The  function  1/Je  defines  the  additional  volume
         of the solution  obtained  per  unit  energy consumption  rate.  Those curves in  fig.
         65  marked  with  index  1 correspond  to  the  case  of the  linear  dependence  K(T)
         in  the whole  temperature range  (Tc  =  oo).  The results of the calculations with
         parameters F" =  10,  L" =  0.1; 0.2; 0.3, are denoted by indices 2- 4,  respectively,
         and the results of the calculations with  F" = 40  and the same L", by indices  5 -
         7.
            It can  be seen  in  fig.  65,  b,  that the function  1/Je  has  a  maximum for  certain
         values of L" and F".  It corresponds to the minimal energy consumption needed to
         obtain additional recovered volumes of fluid, and therefore corresponds to the opti-
         mal electric treatment regime.  Take w; /  (  E"  Q 0 )  and ¢; as the point of maximum
         for  the function 1/Je  and its value 1/Je(we)  there.  In fig.  66, a,  the L" dependencies
