The following information is common to both parts

(a) and (b). Nitrogen flows through a diverging section with \(A_{1}=1.5 \mathrm{ft}^{2}\) and \(A_{2}=4.5 \mathrm{ft}^{2}\). You may assume steady, one-dimensional flow, \(Q=W_{s}=0\), negligible potential changes, and no losses.

(a) If \(M_{1}=0.7\) and \(p_{1}=70 \mathrm{psia}\), find \(M_{2}\) and \(p_{2}\).

(b) If \(M_{1}=1.7\) and \(T_{1}=95^{\circ} \mathrm{F}\), find \(M_{2}\) and \(T_{2}\).
