A converging nozzle is connected to a large tank that contains compressed air at \(15^{\circ} \mathrm{C}\). The nozzle exit area is \(0.001 \mathrm{~m}^{2}\). The exhaust is discharged to the atmosphere. To obtain a satisfactory shadow photograph of the flow pattern leaving the nozzle exit, the pressure in the exit plane must be greater than \(325 \mathrm{kPa}\) gage. What pressure is required in the tank? What mass flow rate of air must be supplied if the system is to run continuously? Show static and stagnation state points on a \(T s\) diagram.
