On this fo.rm list the.averagt daily. unit power level in HHe Net for each day in the reporting month. Compute to the nearest whole mepwatt.

These figures'will be used to plot _a graph for each reporting month. .

Note that when maximum dependable capacity is used for the net electrical  !

rating of the~ unit there may be occasions-when the da'ily. average power .

level cu:eeds the 100% line-(or the restricted power level'11ne). _. In j

such cases the average' daily unit power output sheet should be footnoted.
