A gas turbine power plant which will be powered by a heat source having a
temperature of at least 840·C is to be designed with a pressure ratio of 4.
Regeneration is to be incorporated into the power piant design and it is expected
that the regenerator effectiveness will be at least 90%. It is intended that the
working fluid will enter the compressor at 100 kPa and 15°C. Using air-standard
cycle analysis, calculate the minimum thermal efficiency of the power plant.
