4. In Figure 4, points 1 and 2 represent flows on the same Rayleigh line and are located such that s, = s2, as shown. Now imagine that we take the gas under consideration at 1 and isentropically expand it to 3. Further let's imagine that the gas at 2 undergoes an isentropic compression to 4.If 3 and 4 are coincident state points (That is, T3 =T4),determine whether A3 must be greater than, equal to, or less than A4? Show all of your work and assumptions. Rayleigh Line 2

4. In Figure 4, points 1 and 2 represent flows on the same Rayleigh line and are located such
that s, = $2, as shown. Now imagine that we take the gas under consideration at 1 and
isentropically expand it to 3. Further let's imagine that the gas at 2 undergoes an isentropic
compression to 4.If 3 and 4 are coincident state points (That is, T3 =T4),determine whether A3
must be greater than, equal to, or less than A4? Show all of your work and assumptions.
