The air is compressed to 750 kPa and 550 K. After the combustion process (into theturbine) the temperature is 1300 K and the pressure 750 kPa. The turbine has an isentropic efficiency of 88%.The pressure at the turbine outlet is 100 kPa.

Hello Sir,Good Evening.I have a question in my homework related thermodynamics lesson.The following below is my question. Please advice, thank you
A 120 MW gas turbine power plant running on Ideal Brayton cycle has the followinginitial conditions; air at 22°C & 95 kPa. The compression ratio is 7 and the temperature atthe turbine entrance is 910°C. Determine the following: a. Pressure & temperature at each stateb. T-S diagramc. Heat Added, per unit mass
(b) Derive an expression for thermal efficiency of ideal Brayton cycle
I need the answer as soon as possible
The ideal air-standard Brayton cycle operates with air entering the compressor at 95 kPa, 22°C. The pressure ratio rp is 6:1 and the air leaves the heat addition process at 1100 K. Determine the compressor work and the turbine work per unit mass flow, the cycle efficiency, the back work ratio, and compare the compressor exit temperature to the turbine exit temperature. Assume constant properties.
Consider an ideal Brayton cycle operating on air. The inlet to the compressor is 300 K, 100 kPa. The compressor and turbine pressure ratios are 10. The maximum temperature in the system is 2000 K. Treat the air as an ideal gas with constant specific heats. a. What is the efficiency of this cycle? (Note: see derivation in section 10.1) b. What would the efficiency be for a Carnot cycle operating between the same temperature limits? c. You should have found that the efficiency of this cycle is less than the Carnot efficiency. So, there must be some irreversibility and entropy generation. For each of the four processes (compressor, heat addition, turbine, heat rejection), find the entropy generation per kg of air. For this analysis, assume the best-case scenario – heat is transferred to the high-T heat exchanger from a reservoir at 2000 K and heat is removed from the low-T heat exchanger to a reservoir at 300 K. d. If entropy is generated during this cycle, where does it go? e. What is…
