Extrait du sujet

1. The density changes in a longitudinal pipe of length L, and its area A, due to temperature variation and other reasons, can be approximated as: ρ(x,t) ρ0 = ( 1 − x L )2 cos t t0 Express the mass flow in and/or out, and the mass in the conduit as function of time. Write the expression for the mass change in the pipe.

2. 1.

   Determine the different parameters (Pressure, Temperature, Density, Sound velocity, Mach number and gas velocity) a. At the combustion chamber (3 marks) b. At the throat cross-sectional area (3 marks) c. At the nozzle exit (3 marks)
