Can this be? The Hydrogen bottle lost 25 bar of pressure and about 42
grams of hydrogen between April and September.
Does this make sense?
Well the following table is what the conditions might have been of the
bottle;
Presumed the contents of the bottle is 150 liter and the constant for
this specific case is assumed 40;
other numbers work as well, as long as the data in all fields in the
same column for Volume and Constant is kept all the same.
I leave it up to you to decide if this is feasible.
Date Pressure Volume Boyle Temp
Bottle P*V/T P*V/c
(bar) (liter) (deg. K) (deg. C)
April 19, 2011 85 150 40 318,75 45,6
April 28, 2011 85 150 40 318,75 45,6
September 7, 2011 60 150 40 225 -48,15
The difference in 42 grams is easily explained; Rossi has done several
other tests in the period between April 28 and September 7, in fact
between April 19 and April 28 most likely also a test was performed by
Rossi, due to the difference of 0.3 grams.
Kind regards,
