b. What must the stagnation pressure be at the exit plane? c. At the entrance to the jet arm (2) the fluid velocity is 150 m/s. What are the temperature and pressure at this point? d. Assuming the jet exhausts vertically downward from the two nozzles, estimate the vertical thrust of this jet pack device? e. If a CD nozzle is used and the stagnation pressure increases to 8 bar, what exit Mach number could be achieved if the nozzle is run at the design condition. What is the required exit area if the throat area is 10 cm. How does the vertical thrust change for this configuration
