Abstract

The effects of the fluid flow are usually neglected in acoustics when the relations between the excess pressure and excess density are considered. A particular relation has been derived between the pressure and density which includes streaming. From general thermodynamic point of view a non-absorbing ideal fluid is considered. The flow term as well as the changes in the resistive (or aiding) term is neglected then the result derived satisfy the static derivation for more complex media.
