Gas turbines use hot gases generated directly from the combustion of fossil
fuels. The hot gas expands
through the blades on the turbine rotor causing them to move. The gas turbine process is: 3-4 irreversible but approximately adiabatic expansion of combustion gases
The work output of the turbine is:
where m=mass flow of hot gases h3=enthalpy of hot gases at inlet h4=enthalpy of exhaust gases
