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:

Unformatted text preview: a. The compressor work b. The turbine work c. The thermal efficiency d. 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...
