How Can I Calculate Flow Pressure Drop in a Two-Dimensional Diffuser?

[me_ia]

Hey!
I need to calculate the flow pressure drop inside a two dimensional diffuser (please see image below).

The average flow velocity at the inlet is 0.095 m/s.
The fluid is air at a temperature T=373K .

I can't find any close model at any fluid dynamics handbook.

Does anyone know how can I calculate this?

I will highly appreciate any kind of help!
Thanks!

The schematic is not very helpful, at least for me. Can you make a new, more clear one?

I hope this is clearer:

Much more clear now. You have the Mass flow at the inlet which should be equal to the mass flow at the outlet.
Q(in) = Q (out). From this you can compute the outflow velocity (and you already have the inflow velocity).
Then, provided the flow is incompressible, you have Bernulli's equation to calculate the pressure drop...
Which fluid mechanics book do you use?

I will do so... thanks very much!

Which fluid mechanics book did you say you use?

I use non at the moment, do you recommend a specific book?

I asked because I found it quite strange what you said that you can't find any similar example at any fluid dynamics handbook...
I would recommend the book Fluid Mechanics by Kundu and Cohen or the Fundamentals of Fluid Mechanics by Munson.
