Problem 1 (Marks 3) Smithfield power station in NSW, Australia operates on 4 gas turbines. Each of the gas turbine unit operates on the regenerative Brayton Cycle between the pressure limits of 100 kPa and 700 kPa. Air enters the compressor at 30°C at a rate of 12.6 kg/s and leaves at 260°C. It is then heated in a regenerator to 400°C by hot combustion gases leaving the turbine. Diesel fuel with heating value of 42,000 kJ/kg is burned in...
