From: George Kidder <gkidder@-----.net> Subj: [kl] Gas flow rate in clarinet Date: Sat, 19 Dec 1998 16:46:09 -0500
Relative to the discussion lately about the effects of various gasses on
intonation, I have in mind attempting some experiments, since I will have
access to the necessary equipment. In order to plan these, I need to know
the normal air flow rate through a clarinet while it is being played,
because this will affect the design of the experiments. So my questions are:
1) Does anyone know the value(s) for "normal" flow rates, or where this
information might be found in the literature, or how the measurements were
made. (Sticking a cork in the bell with a tube to a flow meter seems
unlikely; I would think it would seriously affect the intonation, resistance
and everything else.)
2) Does anyone know of measurements of carbon dioxide concentrations in the
bore of a clarinet (or other instrument) during use? If so, where are they
published?
3) Does anyone know of any published work on gas-replacement (nitrogen,
argon, etc.) with wind instruments?
I realize that these technical discussions are not everybody's cup of tea,
so maybe if you have information you can email me privately.
