A flow of 0.02 kmol/s methane, CH₄, and 200% theoretical air, both at reference conditions, are compressed separately to P₃ = P₄ = 2 MPa, then mixed and then burned in a steady-flow setup (like a gas turbine). After combustion, state 6, heat transfer goes out, so the exhaust, state 7, is at 600 K.

a. Find T₃, T₄, and T₅.

b. Find the total rate of irreversibility from inlet to state 5.

c. Find the rate of heat transfer minus the work terms ( ˙Q − ˙W ₁ − ˙W ₂).
