Question
Methane gas (CH4) enters the combustion chamber of a gas turbine at 77°F, 40 lbfi/in² and a molar flow rate of 1.7 lbmol/h and burns
completely with air entering at 300°F, 40 lb/in². The combustion products leave the combustion chamber at T3 = 1380°F, 40 lbf/in².
The gas turbine operates adiabatically at steady state and air can be modeled as 21% O2 and 79% N₂ on a molar basis.
Step 1
CH4 at 77°F,
40 lbf/in²
n = 1.7 1bmolh
X Your answer is incorrect.
n =
Air
P2 = 40 lbf/in²
T₂ = 300°F
