1) A Brayton Cycle produces 14 MW with an inlet state of 17°C and 100 kPa. The compression ratio is 16:1. The heat added in the combustion is 960 kJ/kg. What is the highest temperature and mass flow rate of air? 2) An ideal air-standard Brayton cycle in which the air into the compressor is at 100kPa and 20°C. The pressure ratio across the compressor is 12:1. The maximum temperature in the cycle is 1100°C. The air flow rate is 10 kg/s. Assuming constant specific heat for the air determine:

The thermal efficiency if an ideal regenerator was incorporated 3) A gas-turbine power plant operating on an ideal Brayton cycle has a pressure ratio of 8. The gas temperature is 300 K at the compressor inlet and 1300 K at the turbine inlet. Assuming a compressor efficiency of 80% and a turbine efficiency 85% determine: a. The back work ratio b. The thermal efficiency c. The turbine exit temperature...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
