Pipe lenghth

I know someone has posted a chart of tube length depending on the pitch of the horn... Can't seem to find it in search with the words I'm using... Can I get a little love from the community here?

It was a list of overall bugle length, and the length of each circuit. rough idea, 18 ft for BBflat, 1st valve 30 inches, 2nd valve 16.4 etc....

You could look at Valve Circuit Lengths from 2009, where Dan Schultz provides some numbers about half a dozen posts down. There's more to be found on this, I only looked at a couple of the first half dozen results of google "bugle length" site:chisham.com. For an example of a thread that gets into the complexities, see Tuba 'bugle' length question.

Not concise by any means but a descent place to start. Decimals are merely interpolations:

G Contra tuba 22.5 ft. open pipe
BBb Tuba 18 ft. open pipe
CC Tuba 16 ft. open pipe
F Tuba 12 ft. open pipe
Eb Tuba 13.5 ft. open pipe
Bb Euph/Tenor Trombone - 9 ft. open pipe
Bb trumpet/cornet - 4.5 ft. open pipe

Tuba tuning circuit lengths:
Valve tubing lengths:
F
1st valve = 18"
2nd valve = 8"
3rd valve = 27"
4th valve = 48"

Eb
1st valve = 20"
2nd valve = 9 1/2"
3rd valve = 29 1/2"
4th valve = 52"

CC
1st valve = 23.7"
2nd valve = 11.257"
3rd valve = 34.957"
4th valve = 61.62"

BBb
1st valve = 26.66"
2nd valve = 12.66"
3rd valve = 39.32"
4th valve = 69.32"

This explanation is a bit more truncated, but more - well - musical...
