The previous work on sound power calculation in the presence of a mean flow has been focused on the casting of the basic acoustic equations in the form of an acoustic energy conservation law from which a definition of the acoustic intensity is extracted. The present paper shows that such definitions of sound intensity are deducible from the physical definition of sound power. Also presented is an expression or the sound power in a narrow pipe with a uniform mean flow. (C) 2000 Academic Press.
