Yes, right. I wanted to draw speed line for that blade. That means now I have to take mass-flow on the exit if i want get back same efficiency on speed-line?

Hello,

I have updated this boundary condition & have few blades with same exit corrected mass flow, even though there abs mass is varied.

I have two basic queries:

1. What is forced CFX to...

So this expression would be enough:

T02=massFlowAve(Ttotstn)@R1 Outlet
P02=massFlowAve(ptotstn)@R1 Outlet
Wabs = 1.517 [kg s^-1] ;
massflow= Wabs*((sqrt(T02 /288.15 [K])/(P02/101325 [Pa])) ...

I wanted to impose same boundary condition, my question is that I know Wabs, but Ptout and Ttout would be updated in every iteration?
So i need to write expression to update it in every iteration?
