Problem $7$: Air enters a supersonic nozzle with total temperature of $1300C,$ respectively. The

surrounding static pressure is $40$ kPa and the nozzle is operating at fully expanded mode with an exit

velocity of $750\frac{m}{s},$ if efficiency of the nozzle is $93\%,$ find:

a$-$ the inlet total pressure and exit Mach number of the nozzle.

b$-$ The mass flow rate of air if the exit diameter of the nozzle is $0\mathrm{.}38$ m $.$ Consider adiabatic process

with $Cp=1\mathrm{.}11k\frac{J}{k}g.K$ and $=1\mathrm{.}36.$
