Air at 403 K and 1 atm enters a convergent nozzle at a velocity of 150 m/s and expands isentropically to an exit pressure of 76 kPa. If the inlet area of nozzle is 5x10-3 m2
, find (a) stagnation temperature, pressure and enthalpy, (b) inlet Mach
number (c) exit temperature, pressure, Mach number and area, (d) what must be the
back pressure, temperature, and flow rate if sonic conditions are attained at exit.
Assume air to be perfect gas.
