A small, low-emission, stationary gas turbine engine operates at full load (3950 kW) at an equivalence ratio of 0.286 with an air flowrate of 15.9 kg/s. The equivalent composition of the fuel (natural gas) is C 1.16 H 4.32 . Determine the fuel mass flowrate and the operating air- fuel ratio for the engine.
