B. Consider the flow of air through a convergent-divergent duct, with inlet, throat and exit areas are 6, 4 and 5 m2, respectively. The inlet and exit pressure are 1.01X105 N/m2 and 1X105 N/m2, respectively. Calculate the flow velocity at the inlet, throat and exit. (assume incompressible flow with standard sea-level density).

(a) A supersonic nozzle is attached to a constant diameter circular duct at its exit The duct diameter is the same as the nozzle exit diameter. Nozzle exit cross section area is three times that of its throat. The gas (k-14, R 287 Jg K) enters the nozzle with pressure and temperature of 10 bar and 600 Krespectively with negligible velocity. If a normal shock occurs at a section in the diverging part of the nozzle where the area ratio...
