A small gas turbine uses C8H18(l) for fuel and itenters the combustion
chamber at 25â—¦C whereas air coming from the high pressure stage isat 287â—¦C . The products of combustion leave the combustion chamberat 1167â—¦C . The fuel is injected at a rate of 0.95 kg/min where itis mixed and burned with 400 % excess air. An analysis ofcombustions reveals that all the hydrogen in the fuel burns to H2Obut only 90% of the carbon burns to CO2, with remaining 10% formingCO. Determine:
(a) the phase of the water in the products
(b) the mass flow rate of the air
(c) the rate of heat transfer from the combustion chamber.
