Definitions

  • critical diameter of most fuel sensitized slurries increases as pressure on the slurry increases, at a rate of about 0.07 to 0.1 inches of critical diameter in the slurry, per pound per square inch of pressure increase. That is, a typical slurry of critical diameter d of4 inches at zero or atmospheric pressure may have a d, of about 6 inches at 20 p.s.i.g.
  • FIG. 5 shows graphically how the apparatus of FIG. 6 may be used to control the feed rate of the gassing agent.
  • the initial feed rate may be adjusted at any desired level such as indicated by the points Q or R. If not changed by the second control 41, the feed would continue at a uniform rate, i.e. on a horizontal line Q or R
  • the rate of rotation of screw 25, FIG. 6, is adjusted to determine the slope of the desired control rate Q or R etc. Determination of (a) initial feed rate Q or R, plus (b) the required pumping time, e.g. 100 seconds, or seconds, or some other time, to fill a borehole thus is used to set controls 21 and 41.
