Explanation:
- Runner of a reaction turbine: The runner of a reaction turbine is a rotating part where the energy of flowing water is converted into mechanical energy.
- Variation in pressure: As water flows through the runner of a reaction turbine, the pressure acting on it would vary from more than atmospheric pressure to vacuum.
- More than atmospheric pressure: Initially, as the water enters the turbine, it experiences a pressure higher than atmospheric pressure. This high pressure is necessary to drive the turbine and generate mechanical energy.
- To vacuum: As the water passes through the turbine and imparts its energy to the runner, the pressure decreases significantly. At the exit of the turbine, the pressure can drop to a vacuum or very low pressure.
- Importance of pressure difference: The pressure difference between the inlet and outlet of the turbine is crucial for the efficient operation of the turbine. It drives the flow of water through the turbine and ensures that energy is transferred effectively.
- Atmospheric pressure: The atmospheric pressure acts as a reference point for the variation in pressure within the turbine. The pressure within the turbine can be higher or lower than atmospheric pressure depending on the stage of operation.
Therefore, as water flows through the runner of a reaction turbine, the pressure acting on it would vary from more than atmospheric pressure to vacuum, highlighting the importance of pressure differentials in the turbine's operation.
