Statement I: Cavitation occurs at the entrance of the turbine while it occurs at the exit of the pump.
Statement II: In both the cases local pressure at these points falls below the vapour pressure of the flowing liquid.
- a)Both Statement (I) and Statement (II) are individually rue and Statement (II) is the correct explanation of Statement (I)
- b)Both Statement (I) and Statement (II) are individually true but Statement (II) is NOT the correct explanation of Statement (I)
- c)Statement (I) is true but Statement (II) is false
- d)Statement (I) is false but Statement (II) is true
Correct answer is option 'D'. Can you explain this answer?

Cavitation occurs at the exit of the turbine and inlet of the pump because the pressure at these regions can fall below the vapour pressure of the liquid. So the statement (I) is wrong.

Understanding Cavitation in Turbines and Pumps
Cavitation is a phenomenon that occurs in fluid dynamics and is crucial to understand in the context of turbines and pumps.
Statement I Analysis
- Cavitation in Turbines:
- Cavitation typically occurs at the exit of the turbine rather than the entrance.
- This is due to the low pressure created by the high velocity of the fluid as it exits the turbine.
- Cavitation in Pumps:
- In contrast, cavitation occurs at the entrance of the pump.
- Here, it happens because of the drop in pressure as the fluid enters the pump, which can fall below the vapor pressure of the liquid, leading to bubble formation.
Statement II Analysis
- Local Pressure and Vapor Pressure:
- Statement II correctly identifies that in both turbines and pumps, the local pressure falls below the vapor pressure of the fluid, resulting in cavitation.
- This is a true statement but does not serve as an explanation for the first statement since their locations are different.
Conclusion
- Correct Answer: Option D
- Statement I is indeed false because cavitation does not occur at the entrance of turbines; it occurs at the exit.
- Statement II is true since it accurately describes the condition leading to cavitation without explaining the location of cavitation in turbines and pumps.
Thus, the correct interpretation of both statements leads to the conclusion that Statement (I) is false while Statement (II) is true.
