A tank of dry air at room temperature is steadily vented through a converging-diverging nozzle to atmospheric pressure. We desire a flow rate of 0.1 kg/s of gas at Mach 1 exiting the nozzle. Please answer the following questions:
A. Find the pressure required in the tank to achieve this flow speed.
B. Find the velocity of the gas at the exit.
C. What is the exit area of the nozzle?
D. Find the area of the throat required to permit the correct flow rate.
