Consider the gas power cycle shown in the figure below using air as working fluid with constant specific heat ratio k = 1.4. Two isentropic turbines are used in this cycle. The first one is used to drive an isentropic compressor while the second is used to produce a power output. The temperature at the compressor inlet is 300 K and its pressure ratio is 5. A fraction of the flow denoted x is extracted to bypass the boiler. The specific heat addition to the boiler is 1000 kJ/kg. The first turbine inlet temperature reaches thus 1000 K. a. Sketch the cycle on a T-s diagram. b. Calculate the fraction x. c. Calculate the temperature at the second turbine inlet. d. Calculate the thermal efficiency of the cycle. Burner 1-X х WR C T1 T2
