Problem 2: Known: The gas turbine cycle working under the principle of Brayton cycle (a) Explain about the general theory related to the Gas turbine power plant? (b) Formulate to determine the amount of heat rejected? (c) Determine the thermal efficiency of the cycle? Conditions: The air is compressed at the compressor at a pressure of 120 kPa and at a temperature of 28 "C. The pressure ratio is given as 7. The flue gases enter into the turbine at a temperature of 850 °C. Consider compressor efficiency of 90% and turbine efficiency of 85%. Take y-1.4 and Cp 1.005 KJ/kg K. Scheme and given data: Compressor 120 kPa 28°C. Combustion chamber 850°C Turbine
