Thank you so much for that explanation. Regards.

Thank you for your response. I still believe there is a major catch to this question, since it's unsteady flow and hence the control volume boundary fluctuates. Anyone else with ideas. I've been looking through textbooks and can only find a question with a straight pipe that's similar to...

[PLAIN]http://img811.imageshack.us/img811/4882/stumped.png So from the above question I presume that the relation (Density)x(Area1)x(Velocity1)=(Density)x(Area2)x(Velocity2), cannot be applied due to the flow being unsteady and thus the control volume changing with time. I've read up about...
