Q4) A gas turbine unit is used to produce power during peak demand. The turbine provides power to the air compressor and the electric generator. The air inlet to the compressor is at 100 Kpa and 20 C that is compressed to 800 Kpa and 260 C with mass flow rate of 0.3 Kg/s. The heat lost in the compressor is 120 KJ/kg. The compressed air is mixed with a fuel to produce a 0.8 Kg/s of supper heated steam at the turbine input (h3 = 7500 KJ/Kg) while the outlet of the turbine has a saturated liquid- vapor mixture (h4 = 2800 KJ/Kg) with a heat loss of 250 KJ/kg throughout the turbine walls. Calculate: I. The necessary power input to the compressor II. The total power produced by the turbine C 2 Combustion chamber 3 V3 = 100 m/s T V4= 40 m/s GEN
