A converging-diverging nozzle (Figure P5.16) discharges air into a receiver where the static pressure is (15 mathrm{psia}).

Question:

A converging-diverging nozzle (Figure P5.16) discharges air into a receiver where the static pressure is \(15 \mathrm{psia}\). A \(1-\mathrm{ft}^{2}\) duct feeds the nozzle with air at \(100 \mathrm{psia}\), \(800^{\circ} \mathrm{R}\), and a velocity such that the Mach number \(M_{1}=0.3\). The exit area is such that the pressure at the nozzle exit exactly matches the receiver pressure. Assume steady, one-dimensional flow, perfect gas, and so on. The nozzle is adiabatic and there are no losses.
