Problem 48P

Is it realistic to assume that the propagation of sound waves is an isentropic process? Explain.

Step-by-Step Solution:

Step 1</p>

The isentropic assumptions are only applicable with ideal cycles. Real world cycles have inherent losses due to inefficient compressors and turbines. The real world system are not truly isentropic but are rather idealized as isentropic for calculation purposes.

Step 2</p>

The isentropic flow process is  defined as being both adiabatic and reversible. These conditions are very nearly met in one-dimensional, nonviscous, shock-free flow where both the cross-sectional area of the streamtube and the flow direction are constant or change very slowly. The non-viscous assumption is extremely important when flow in a channel is considered, since, in reality, boundary layer interaction causes irreversible changes in flow properties, complicating analysis.
