Question 398: Waves

Question

If the end correction of an open pipe is $$0.8 \mathrm{~cm}$$, then the inner radius of that pipe is

Accepted Answer

For an open pipe, $$\mathrm{e}=0.6 \mathrm{~d}$$
$$\begin{array}{ll}
	herefore & \mathrm{d}=\frac{\mathrm{e}}{0.6} \
	herefore & 2 \mathrm{r}=\frac{\mathrm{e}}{0.6} \
	herefore & \mathrm{r}=\frac{0.8}{1.2}=\frac{2}{3} \mathrm{~cm}
\end{array}$$
