How this translates into figures 20010 shown in the table see picture gallery.

Chemical Safety Board; Picture: As a result, passing through the in-line resonance is possible, if the process medium is gaseous and the range of the in-line resonance does not fall within the continuous operation of the plant. The revision provides some clearer and more-detailed definitions. Scientific Image of the Day: This same remained unchanged for more than 20 years.
