Consider the subsonic flow through a divergent duct with area ratio \(A_{2} / A_{1}=\) 1.7. If the inlet conditions are \(T_{1}=300 \mathrm{~K}\) and \(u_{1}=250 \mathrm{~m} / \mathrm{s}\), and the pressure at the exit is \(p_{2}=1 \mathrm{~atm}\), calculate:

a. Inlet pressure \(p_{1}\)

b. Exit velocity \(u_{2}\).
