Oxygen with \(T_{t 1}=1000^{\circ} \mathrm{R}, p_{t 1}=100 \mathrm{psia}\), and \(M_{1}=0.2\) enters a device with a cross-sectional area \(A_{1}=1 \mathrm{ft}^{2}\). There is no heat transfer, work transfer, or losses as the gas passes through the device and expands to 14.7 psia.

(a) Compute \(ho_{1}, V_{1}\), and \(\dot{m}\).

(b) Compute \(M_{2}, T_{2}, V_{2}, ho_{2}\), and \(A_{2}\).

(c) What force does the fluid exert on the device?
