Acoustic impedance water surface in partially filled tank

  1. Dec 8, 2015 #1
    Hello guys,

    Consider a partially filled tank with water where the acoustic field can be described by the Helmholtz equation.

    The boundary condition at the water surface would be [tex] \frac{∂p}{∂\vec{n}} = -j\rho_0\omega\frac{p}{Z} [/tex]
    where Z is the impedance of the water surface.

    What would be the impedance of the water surface.? Are there any models i could use?

    Thanks for your answers!

    Are you sure is the impedance of water surface?
    Isn't the specific impedance of water?
