Hi guys, I had a question about aspen since I am using it for my design project. I am simulating a HRSG and was wondering how I would find the efficiency so I can see how it changes when changing temps of evap, econ and superheater?

I have attached what I have so far, the current issue I am facing is that the volume of steam (under the results summary for all streams) only changes when I change the final steam temp and not any of the other temps.

Any help would be greatly appreciated.
