A thought accrued to me concerning burner noise and the high pitch some burners make.
I was drawing up the venturi tubes for my burner. I was always lead to believe the tube diameter to length should be 6.5 X diameter.
I checked two original Stanley burners I have and one has 1-5/8 diamenter by 13.5 long tubes, thatís 8.3 X diamenter another has 1-1/4 diamenter by 10.5 long tubes thatís 8.4 X diamenter
I did a drawing on an baker burner that one of our SACA members has appart and the tubes were 2-1/2 diamenter by only 13 inch long and thatís only 5.2 X diamenter. Very short tube length.
I was woundering if the higher pitch noise on some burners is do to a short tube length to diamenter.
When you make steam whistle the longer the length the deeper the tone, the shorter the higher pitch.
