The compressor has an isentropic efficiency of 80 percent, and the turbine has an isentropic efficiency of 90 percent. Assume constant properties for air at 300 K with Cy= 0.718 kJ/kg-K, Cp = 1.005 kJ/kg-K, R=0.287 kJ/kg-K, and k=1.4. If the net power output is 130 MW, determine the volume flow rate of the air into the compressor in m³/s. (You must provide an answer before moving on to the next part.) The volume flow rate of the air into the compressor is m³/s.
