Consider an ideal gas turbine cycle with two stages ofcompression and two stages of expansion.  The pressureratio across each compressor stage and each turbine stage is 5 to1. The pressure at the entrance to the first compresor is 100 kPa,the temperature entering each compressor is 25°C (298 K), and thetemperature entering each turbine is 1100°C (1373 K). An idealregenerator is also incorporated into the cycle.  For theair involved, it may be assumed that Cp = 1.005 kJ/kg.K and thespecific heat ratio, k = 1.4.
(a) The compressor work is __ kJ/kg. (b) The turbinework is __ kJ/kg. (c) The cycle efficiency is __%.
