Effect of Frequency on the end Correction of Pipes

Using Blaikley's method, the end corrections of "closed" pipes have been determined for pipes of brass, with walls 0.12 cm thick and the inside diameter 9.92 cm, 7.36 cm and 4.84 cm respectively, over a range of frequencies from 128 vps to 1715 vps, and over a range of $\frac{\lambda }{D}$ (wave-length/diameter) from 27 to 4. An electrical detector was used for determining the resonance peaks, which makes this work ten times more accurate than any formerly reported. The highest frequency used with each pipe was the limiting frequency for which resonance could be obtained, and in each case was such that $\frac{\lambda }{D}=4\mathrm{}$ approximately.
