A closed pipe of length $L$ (gas density $ρ_{1}$ ) and an open pipe (gas density $ρ_{2}$ ) have equal compressibility and equal fundamental frequencies. The length of the open pipe is:

Options:

Answer:

Solution:

Closed fundamental $v_{1} /4 L$ equals open fundamental $v_{2} /2 L'$ , so $L' = 2 L v_{2} / v_{1} = 2 L ρ_{1} / ρ_{2}$ .
