cal questions (30 points) While testing rocket nozzles at sea level, the following information was gathered. The exhaust gases at the exit are flowing at Mach 3.7. The total burn time was 40 sec and the final mass was recorded at 215 kg. The propellant mass fraction is 0.82 while the mass ratio is 0.18. The combustion pressure is 7 MPa and the throat area is 0.00574 m². Assume that the specific heat ratio is 1.3, the gas constant is 287J/kg*K, and the mass ratio is the ratio between final mass and initial mass. a. Find exit velocity b. Find thrust C. Find specific impulse
