Ted Bowman writes, "... Mr. DeWitt's blower is more than enough for
a rank of violin pipes.  Obviously, a rank of trombones needs more
wind than a flute."

Actually, the opposite is correct.  Flutes require more air flow
than Trombones.  Flow = Pressure / Resistance  (which is why loss
of resistance damages organ blowers).
