The overall efficiency of thermal power plant is equal toa)Rankine cyc...




Explanation:




Boiler efficiency x turbine efficiency x generator efficiency


  • Boiler efficiency: The efficiency of a boiler is the ratio of useful heat output to the heat input provided to the water. It is an important factor in determining the overall efficiency of a thermal power plant.

  • Turbine efficiency: The efficiency of a turbine is the ratio of the actual work produced by the turbine to the theoretical work that could be produced. It plays a crucial role in converting the thermal energy of steam into mechanical work.

  • Generator efficiency: The efficiency of a generator is the ratio of the electrical power output to the mechanical power input. It is essential for converting the mechanical energy produced by the turbine into electrical energy.



By multiplying the boiler efficiency, turbine efficiency, and generator efficiency, we obtain the overall efficiency of a thermal power plant. This formula takes into account the efficiency of each component in the power generation process and provides a comprehensive measure of the plant's performance. Therefore, option 'D' is the correct answer as it considers all the key factors that contribute to the overall efficiency of a thermal power plant.
