Question

As the Thermal Engineer for Saudi Aramco, you are tasked with designing an upcoming gas powerplant in Jubail. The gas power plant has two stages of compression and two stage of expansion.Design the gas power plant working as a non-ideal Brayton cycle by determining the overall pressure ratio required to optimize the net power output of the cycle (Hint: Vary the overall pressure ratio from 5 to 25 in small steps of 0.5 to identify the optimum overall pressure ratio that gives maximum net power output. Overall pressure ratio = Highest pressure/ lowest pressure inthe cycle). Both stages of the compressor and the turbine have the same pressure ratio. Consider cold air-standard assumptions for the analysis. The inlet temperature for both compressor stages is 300 K and the inlet pressure for the first compressor stage is 100 kPa. The maximum cycle-temperature is given below for your KFUPM ID number (see in bold). The isentropic efficiency-of the turbine is 95% while that of the compressor is 82% and the air flow rate is 100 kg/s. a) Draw a T-s diagram for the cycle showing all states and include a table listing the pressure and temperatures at each state for the optimized pressure ratio. b) Determine the back work ratio and the thermal efficiency of this gas-turbine cycle at theoptimized point. c) Determine the daily energy output of the gas power plant in kWh considering that it operates-for 24 hours each day and the gas flow rate is 100 kg/s (Hint energy output = Power output XNumber of hours). d) Assuming that each house consumes 100 kWh per day, calculate the number of houses that-can be powered by the above gas power plant.
