Air enters the combustor of a gas-turbine engine at a total temperature T0 of 500 K. The air stream is split into two parts: primary and secondary streams. The primary stream reacts with fuel supplied at a fuel-air ratio of 0.05. The resulting combustion products are then mixed with the secondary air stream to obtain gas with total temperature of 1550 K at the turbine inlet. The fuel has a heating value of 42 MJ/kg. The specific heats of air and combustion products are taken as cp = 1 kJ/kg/K.
If the sensible enthalpy of fuel is neglected, the temperature of combustion products from the reaction
of primary air stream with fuel is approximately
A
2100 K
B
3200 K
C
2600 K
D
1800 K

Correct : c
