A converging–diverging nozzle with a 4:1 exit-area ratioand p0 = 500 kPa operates in an underexpanded condition as in Fig. The receiver pressureis pa = 10 kPa, which is less than the exit pressure sothat expansion waves form outside the exit.

An ideal gas is to flow isentropically from a large tank where the air is maintained at a temperature and pressure of 59 °F and 76 psia to standard atmospheric discharge conditions in a way to achieve a maximal velocity. Describe in general terms the kind of duct involved and determine the duct exit Mach number and velocity in ft/s if the gas is air. The problem can be solved either using the isentropic relations or this figure. The isentropic relations are more accurate, but difficult to use unless you code them into a computer program.
