The actual candle-power developed by each burner was not quoted by
Neuberg, and has accordingly been calculated from his efficiency values.
It is noteworthy, and in opposition to what has been found by other
investigators as well as to strict theory, that Neuberg represents the
efficiencies to be almost identical in all sizes of the same description
of burner, irrespective of the rate at which it consumes gas.
Writing in 1902, Capelle gave for Stadelmann's twin injector burners the
following figures; but as he examined each burner at several different
pressures, the values recorded in the second, third, and fourth columns
are maxima, showing the highest candle-power which could be procured from
each burner when the pressure was adjusted so as to cause consumption to
proceed at the most economical rate.
