Honestly, I don't understand why you need to know my name...However, I suppose you're asking for the sources of information about the data and the formulas used. As I clearly state, my main sources are Wikipedia, Google and an old textbook of physics that I used when I was in high school (since then I've sold the textbook, and I don't remember the title; I'm italian, and so it was the book).There is something I'm missing? Because for as long as I can think about, I don't seem to find a reason to give you my name.

Actually, the speed of sound should be in m/s, and the resulting length is in meters, so 0.15 m = 15 cm, as expected.The formula works for any kind of units system, as long as you keep them consistent for all your calculation; replacing each variable with its unit you can easily see that fact:1. [meters] = [meters/second]/[1/second]2. [centimeters] = [centimeters/second]/[1/second]3. [yards] = [yards/second]/[1/second]4. [inches] = [inches/second]/[1/second]and so on...

Hi! The diameter of the pipes will not interfere with the frequency: as you can see, the frequency f is related only to the speed of sound v and the pipe length l.If you know the frequencies you need you can just plug those values into the formula along with the speed of sound, and you'll have all the length you need.You can also use the spreadsheet I've prepared that will make al calculation for you. You can reach it from the last step.Regards!
