Open Specific Steady-State Devices>Brayton Cycle back
A gas turbine power plant operates on a simple Brayton cycle with air as the working fluid. The air enters the turbine at 1 MPa and 1000 K and leaves at 125 kPa, 610 K. Heat is rejected to the surroundings at a rate of 8000 kW and air flow rate is 25 kg/s. Assuming a compressor efficiency of 80%, determine the net power output and the thermal efficiency. Assume constant c_p.

What-If Scenario: How do the answers change if the compressor efficiency is increased to 90%? 

Solution: Step-by-step instructions as well as the TEST-Code can be found in the Tutorial>Daemons>OpenCycle>Practice page. An image of the I?O panel is reproduced from the Slide Show below.
