1. Are the equations for quasi-1-D flow exact? Explain your answer.
2. A) What is the quasi-1-D form of the mass conservation relation?

3. B) For subsonic quasi-1-D flow, what will happen to the velocity if the area is reduced?

   3. For supersonic quasi-1-D flow, what will happen to the velocity if the area is reduced? 4.What geometrical feature must be present in order to accelerate an initially subsonic flow to supersonic speeds in a duct with a slowly varying area?

   1. 5)What does it mean for the flow in a nozzle to be choked?
