A stationary gas turbine power plant operates on a simple ideal Brayton cycle with air as the working fluid. The air enters the compressor at 95 kPa and 290 K and the turbine at 760 kPa and 1100 K. Heat is transferred to the air at a rate of 35,000 kW. Determine the power delivered by this plant.
1) Assuming constant specific heats at room temperature2) Accounting for the variation for specific heats with temperature
The die characteristic is Q_x = 0.0015p where p is the head pressure in psi. Determine the flight angle that maximizes the flow rate Q_x and graph it.
