A gas$-$turbine power plant operates on the regenerative Brayton cycle between the pressure limits of $100$ and $700$ kPa. Air enters the compressor at $30\backslash$deg C at a rate of $12\mathrm{.}6$ kg$/$s and leaves at $260\backslash$deg C$.$ It is then heated in a regenerator to $400\backslash$deg C by the hot combustion gases leaving the turbine. A diesel fuel with a heating value of $42,000$ kJ$/$kg is burned in the combustion chamber with a combustion efficiency of $97$ percent.
