Astationary 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 air at a rate of 35,000 kj/s. determine the power delivered by this plant (a) assuming constant specific heats at room temperature and (b) accounting for the variation of specific heats with temperature.
