Brayton Cycle Thermodynamic Analysis

Hi! I'd appreciate some help solving the thermodynamic's problem. Im sorry if the problem statement isn't 100% clear, as I've translated it from my native language.

I'd really like if you could help me check my equations/procedure/results.

In the following link both my attempted solutions and problem diagram can be found.

1. Homework Statement

A gas turbine operating under a modified brayton cycle.
Air is compressed at a ratio of 9.
Air enters the compressor at 273K and 100kPa.
The cycle's maximun temperature is 1600K.
Assume that the turbines and compressor operate adiabaticaly and reversibly.
The first turbine is used to power the compressor.
air mass flow is 100kg/s

Homework Equations


Determine temperature and pressure at state 4
determine net power
determine maximum power by exergy analysis

The Attempt at a Solution


I've solved the problem using both ideal and real methods. I'm concerned that while some of the data between the two is very similar (work from compressor and HP turbine), other stuff is quite different (heat lost and introduced, max power)


Thanks!

Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
