Calculate airflow required for the gas turbine and the sfc

The following data apply to the auxiliary power unit (APU) on the Boeing 777 (single-shaft unit, driving separate load compressor and generator):

Load Compressor

Mass Flow 3.5 kg/s

Pressure Ratio 3.65

Isentropic efficiency 0.88

Gas turbine

Pressure ratio 12.0

Compressor isentropic efficiency 0.84

Turbine inlet temperature 1390 K

(Combustion deltaP)/(compressor delivery pressure) 0.05

Turbine exhaust pressure 1.04 bar

When operating at 35?C and 1.01 bars at take-off conditions, the unit must supply 200 kW electrical loads.
Calculate the airflow required for the gas turbine and the SFC?
