Homework Statement
Hello-
I'm having trouble understanding a problem:
Consider a sealed 1D pipe of length L. At t=0, v=0 everywhere and the pressure is given by: P=P_0 +δP
and δP = (p-bar)x/L
P_0 and (p-bar) are both constants.
and I'm supposed to find density (ϱ) as a function of x and t.
I don't understand why I'm given the pressure, and how to find δϱ.
Homework Equations
The Attempt at a Solution
Using the boundary conditions, I have an expression for the velocity with sin terms. But I don't know how to use that to find the density as a function of (x,t).
