Gas Consumption

The gas consumption was measured in te beamtime 1999 over 1 week.
The Excel file can be downloaded. The gas
pressure as a function of time is plotted here and can be downloaded as
PS-file.

The linear fit of the data points give us a function: **p(t)[bar] =
0.36 t[days] + 5.47 [bar]. **This means, that we have decrease in the
bottle pressure (== gas consumption) of 0.36 bar / d.
