9-97 A stationary gas-turbine power plant operates on an ideal regenerative Brayton cycle (P = 100 percent) with air as the working fluid. Air enters the compressor at 95 kPa and 290 K and the turbine at 760 kPa and 1100 K. Heat is transferred to air from an external source at a rate of 75,000 kJ/s. Determine the power delivered by this plant a) assuming constant specific heats for air at room temperature and b) accounting for the variation of specific heats with temperature. | |
