5. (20 points) An infinitely long rigid smooth pipe of cross sectional area A, = 1.0 m² is connected with another infinitely long main pipe as shown in the figure. If the cross-sectional area of the main pipe is A = 4.0 m², find the sound power transmission coefficient in the main pipe (T) and the branch pipe (Tz,b) (Hint: At x = 0, P; + Pr = P₁ = P₁, A₁ (u₁ + ₁) = 4₁ 4₂ + Azu₂ ) Ab Ai A A₂ A- **0 14
