After the air compression, the same amount of fuel is added to the combustion chamber, which undergoes combustion. After combustion, the flue gases are expanded in the turbine, which is more than the mass flow rate of only air in the compressor.

Understanding Mass Flow in Gas Turbines
In a single-stage open-cycle gas turbine, the mass flow through the turbine is indeed higher than that through the compressor. This phenomenon is primarily explained by the combustion process occurring in the combustion chamber.
Key Reasons for Higher Mass Flow in Turbine
- Combustion of Fuel:
- The combustion chamber is where fuel is mixed with compressed air and ignited.
- This process significantly increases the energy content of the air-fuel mixture, resulting in a higher density and mass flow rate entering the turbine.
- Expansion of Gases:
- After combustion, the temperature of the gases increases dramatically.
- This high-temperature gas expands when it enters the turbine, contributing to a higher volume flow rate compared to the input flow from the compressor.
- Energy Conversion:
- The turbine extracts energy from the high-temperature gases, converting thermal energy to mechanical energy.
- This process ensures that the mass flow continues to be high in the turbine, as it maintains the momentum of the exhaust gases.
Conclusion
Thus, option 'C' accurately reflects the reason why the mass flow through the turbine exceeds that through the compressor. The combustion of fuel significantly enhances the mass flow due to the increased energy and temperature of the gases, leading to efficient turbine operation.
