Unformatted text preview: r in which the pressure is 500kPa while the back pressure is varied. Determine: (a) the design pressure ratio of the nozzle, (b) the design back pressure, (c) the design Mach number of the nozzle, (d) the minimum and maximum possible Mach numbers at the nozzle throat, (e) the maximum possible mass flow rate through the nozzle (in terms of the chamber temperature), and what range of back pressures will produce this, (f) the range(s) of back pressures will produce a wave free flow. Be sure to show the working behind each of your answers. 3. The lunar descent module used for the Apollo miss...
