# 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!
