"Harmonics are multiples of the fundamental, so F3 (aka F2 in a stopped pipe) = 40*3 = 120 Hz........ "
I think that this simple relationship is only true for straight constant area pipes. If the pipe is tapered or expanding, like a TQWT, the frequency of the harmonics will not be simple multiples of the fundamental frequency.
