In this video we are going to be solving four common problems in compressible fluid mechanics. Each question will cover different areas of fluid mechanics namely; Shock Waves, Sonic Boom, Sound Transmission, Rocket Propulsion, Hypersonic Flight, Fanno Flow, Rocket Propulsion and the Thrust Equation

Timestamps and Questions:

Question 1 at 00:35 Plane passes you at speed of 3500 knots, 1000 feet above. Temperature on PFD = 10 C, After how long do you hear it?

Question 2 at 02:00 Air at M = 5.25 and 35 kPa, at 45 C flows over the inlet ramp of a hypersonic aircraft at an angle of 20 degrees. Calculate the pressure, temperature and velocity of the air beyond the inlet.

Question 3 at 04:50 Air at M = 2.1 and 600 kPa static, flows in a duct that is 0.5 m in dia and 2m long, friction = 0.025, find M and pressure at duct exit

Question 4 at 07:55 Rocket engine stores fuel at 2500 K and 304 kPa, nozzle throat area = 0.1 m^2 and exit area = 1.2 m^2, find the thrust, gamma = 1.3, R = 475 J/kg K, It is fired where the pressure outside = 95 kPa.

About Me: 16:30

I also recommend that you watch my rocket propulsion videos if you are having difficulty understanding how the rocket engine question is solved.

Thanks for watching!
