Homework Statement
Hi there,
I am a beginner in acoustics and there are severals problems I am currently struggling while I was reading the first chapter of "Theory of Vortex Sound" (available on Google books).
Homework Equations
For Q4[/B]:
The Attempt at a Solution
For Q2 and 3, as underlined in the first picture, if the velocity and pressure doesn't go like 1/r , the integral will diverge as r-> inf. However, there are no 1/r terms in U0cos(wt)
For Q4,
I am not sure how to proceed, since the variable y is contained in two terms within the dirac delta,I don't know how to eliminate it.
BTW, I googled sth that might be helpful for Q4.
