A nozzle is moving in the air gas at the speed of u to the -x direction. The air is ingested at the inlet with the radius of rin = 1m at the speed of the u = 10 m/s in the x direction. The air gas is then exhaust at the outlet with the radius of rout= 0.5m. Assume the density p = 1.125kg m of the air gas is unchanged through the nozzle. (a) If the nozzle is static, i.e., u = 0m/s, compute the velocity u at the outlet. Then, compute the thrust generated by the gas acting on nozzle. (8 marks) (b) If the nozzle is moving at the speed of u = 5m/s, compute the velocity u at the outlet. Then, compute the thrust generated by the gas acting on nozzle. (8 marks) Uin Tin U Tout uout
