Air flows isentropic ally at the rate of 0.5 kg/s through a supersonic convergent-divergent nozzle. At the inlet, the pressure is 680 kPa. the temperature 295 K. and the area is 6.5cm^2. If the exit area is 13 cm*2, calculate:
a) The Stagnation pressure and temperature.
b) The exit Mach number
c) The exit pressure and Temperature
d) The area and the verlocity at the throat.
Using static equilibrium calculations, calculate how far from the fulcrum the tweezers must be held to avoid damaging the sliver.
