The following information is known about the steady flow of air through an adiabatic system:

At section \(1, T_{1}=556^{\circ} \mathrm{R}, p_{1},=28.0 \mathrm{psia}\)

At section \(2, T_{2}=70^{\circ} \mathrm{F}, T_{t 2}=109^{\circ} \mathrm{F}, p_{2}\), \(=18 \mathrm{psia}\)

(a) Find \(M_{2}, V_{2}\), and \(p_{t 2}\).

(b) Determine \(M_{1}, V_{1}\), and \(p_{t 1}\).

(c) Compute the area ratio \(A_{2} / A_{1}\).

(d) Sketch a physical diagram of the system along with a \(T-S\) diagram.
