Nozzles in gas turbine electrical generators accelerate the combustion gases to higher velocities by burning a fuel. The combustion products (M = 28 kg-kmol-1, cP = 1.009 kJ-kg-1-K-1) in a natural gas fueled electrical generator enter the nozzles with a negligible velocity at 3.61 MPa, 400 C. They leave at 2 MPa, 327 oC through an exit area of 0.1 m2.
What is the velocity at the outlet of the nozzles?
What is the mass flow rate through the nozzles?
The increase in the flow work of the combustion products is?
