Rackett Equation: For d sat of the Liquid phase d sat = d c × B - (1- T/T c ) N ; where T c and d c are the critical temperature and critical density, respectively.

2013年2月14日 · RANGE: The rackett plays about an octave and a-half (typically a twelfth) on fundamental notes, and can be overblown for higher pitches. The cylindrical bore of the Renaissance rackett causes it to overblow at the twelfth, and the baroque rackett overblows at the octave. It also sounds one octave lower than written.
