    1. Answer: a
      Explanation: Decrease in pressure in any portion of turbine below one third of atmospheric pressure may cause vapour bubbles or cavities to form. This phenomenon is called cavitation. Also to maintain continuity of flow without vaporisation the pressure should not fall below vapour pressure of water.
