B) A gas turbine power plant is designed to develop a power output of 135 MW when operating at ISO conditions: 1.0 bar and 15 °C. The axial flow compressor operates at an optimum pressure ratio. The turbine section consists of two stages, a high pressure turbine to drive the generator and low pressure turbine drives the compressor. Calculate the pressure at exit of high pressure turbine, thermal efficiency, mass flow rate of air and specific fuel consumption using the following data: Tmax = 1192 K, air-fuel ratio = 60 kg of air / kg of fuel, LCV of fuel = 50000 kJ/kg and the hot gases temperature leaving second stage of turbine is limited to 670 K. %3D kJ Take: Cpans = 1.135 kg.K and Ygas = 1.333 %3D
