Consider a drone which is propelled by a solid fuel burning rocket motor. See figure below for a schematic of a solid fuel burning rocket motor. The air exhausting the combustion area of the motor (before the nozzle where the grain is) has a stagnation pressure of 600 kPa and stagnation temperature of 600 K. For all gases in this problem you can assume γ=1.4 and R=287 J/Kg K a. (20 pts) If the motor is coupled to a nozzle which only contains a diverging converging section with an exit area of 0.2 m² calculate the mass flow through the nozzle at an altitude of 2000 m where the atmospheric is 80 kPa b. (10 pts) For the same configuration as part a. what would the mass flow rate be if the drone climbed to an altitude of 8000 m where the atmospheric pressure is 35 kPa c. (10 pts) If the converging nozzle was replaced with converging-diverging nozzle that was designed to operate on design at an altitude 8000 m what would the exit area have to be if the throat area is 0.2 m²? d. (25 pts) Derive an expression and use it to determine the thrust generated by the configuration of part c.

Q1 P1 (1.5 pt.): The manometer shown below is used to measure the pressure at point A. It operates at 20°C and the right side is open to the atmosphere. What is the pressure at point A Oil, SG = 0.85 Water A 10 in 6 in g \gamma_{H_2O} P_{atm} Sl units 9.8 m/s² 9810 N/m³ 101,300 Pa BG units 32.2 ft/s² 62.4 lb/ft³ 14.7 psi Mercury, SG = 13.6 5 in Water Q1 P2 (2 pts.): a) (1.5 pts.) A fire engine pumps water from a pressurized tank through a hose to the top of a ladder. At the beginning of the hose, the pressure is 200,000 Pa (a Pascale is a Newton per meter squared) and the velocity is 1 m/s. If the fire fighter is holding the open end of the hose 6 m above the end connected to the tank, what is the velocity of the water as it exits the hose? b) (0.5 pts.) List the assumptions that you used to answer part a).
