Momentum transport in a converging nozzle...this is from one of the subject that I have to take this semester, Transport Phenomena...I've read lots of articles but the problem is I really dont know where to start...

Hi yasha,

There is always alot of information on many topics that are to be learned in university.  Could you provide a question, and then this way I can try and help you.

I wish you the best,

Eugene

First, always know your assumptions.

The typical assumption for converging nozzle flows is that it is isoentropic:
1. No friction. (reversible)
2. The fluid flows so fast that there is negligible heat transfer. (adiabatic)

On top of the usual mass balance, you can perform an energy and entropy balance.
