Developed length equals .01745 times radius times degree of bend.
i.e. 90 degree bend with a radius of 10 inches equals .01745 x 10 x 90 equals 15.70 or you can use 1.57 as a multiplier for 90 degrees so 10 time 1.57 equals 15.70.

pipe length = 5487mm pipe size = 6inch
each pipe is a different length.... the shorter the pipe the higher the note....the longer the pipe the lower the note...
Area of pipe is: A = Pi X R^2 (pi times Radius Squared) Voume is Area of pipe Times Length of Pipe. Volume = L X A where Length is 288 inches. Volume = 288 X Pi X 4^2 = 14,476 cubic Inches Volume = 8.37 Cubic Feet
The formula for this goes like this: radius of the pipe squared (32) x pi (3.1416) x length of pipe (12) = volume (amount of water). So 32 x 3.1416 x 12 = 339.2928 or about 339.3 cubic inches.
Pipe lengh. a 32' pipe CCCC would produce a ferquency of about 16hz. a 64' pipe CCCCC, 8hz similarly a 16' CCC, 32hz.
