this is the drawing i attach.

i just want to know how to calculate the P2 and V2 and the vacuum if P1=3.4KPa, V1=9.7m/s and T1=51C degree?

please help me guy..i really need the answer asap...i dont know what ot do anymore...i'm blurr..really appreciate for ur guys helps.

maybe I do not fully understand all details and description (e.g. inlet at the point where the vacuum is - I have always thought that the flow is from higher to lower pressure...), but I suggest that the best option for this calculation is buliding a CFD model, geometry is quite simple and it should take much time - using a simple approach for, example based on Bernoulli eqation, it is difficult to account for energy dissipation within this element and your result would not be accurate and reliable
