I don't think I have ever actually used PVC for conveying traditional fluids. This "plumbing" project employed the versatile building material for making modular musical instruments.
In this case, I trying to make a flute that would play in the key of G, but the first try ended up being about a half step sharp (not sure why). So I made another version with a tuning slide, which can just about play on key. Then I realized that I could also make another mouthpiece that was an end blown whistle instead of the traverse blown flute.
And before I knew what was happening, I had a bunch of PVC pipes that where totally useless for plumbing because they are all full of holes.... But if you want to mess up some PVC pipe too, I ill put the general design parameters below.
Have fun and Happy New Year!
/////// General Flute Design for key of G4 \\\\\\\\
3/4 inch Schedule 40 PVC
*Hole 0 (mouthpiece): Diameter: 12.5mm, Distance from end: 395mm
*hole 1 (F#), Diameter: 9mm, Distance from end: 218mm
*hole 2 (E), Diameter: 9mm, Distance from end: 194mm
*hole 3 (D), Diameter: 9mm, Distance from end: 165mm
*hole 4 (C), Diameter: 9mm, Distance from end: 123mm
*hole 5 (B), Diameter: 11mm, Distance from end: 102mm
*Hole 6 (A), Diameter: 8.5mm, Distance from end: 69mm
*End (G), Diameter: NA, Distance from end: 0mm
("End" defined as open side of flute, the side opposite to the mouth piece)
