Question: Problem 1 - Consider a 1 0 MW power gas turbine system with a pressure ratio of 2 0 and combustion temperature of 1 2

Problem 1- Consider a 10 MW power gas turbine system with a pressure ratio of 20 and combustion temperature of 1200 C . Turbine and compressor efficiencies are \(90\%\). The fuel is natural gas, assumed to be close to methane. The exhaust from the turbine is directed into a heat recovery steam generator that produces saturated steam at 200 C . Feed water into the steam generator is at 80 C . The exhaust gas from the boiler is at 220 C .
A - Calculate the air mass flow rate through the plant
B-Calculate thermal efficiency of the plant
C-Calculate the mass flow rate of fuel and fuel air ratio of the system using heating value of methane
D-Calculate the overall efficiency of the plant
E-Calculate the mass flow rate of generated steam
You may assume that the gas properties are similar to air.
