Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Cavitation is a problem in pumps.
It occurs under specific conditions.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand cavitation.
Step 3: Detailed Explanation:
A. Cavitation when pressure is too high - incorrect.
B. Cavitation when pressure is too low - correct.
C. Tendency to cavitate decreases with volatile liquids - incorrect (increases).
D. Cavitation avoided by decreasing pressure drop in suction line - correct.
Thus, B and D are correct.
Step 4: Final Answer:
The correct statements are (B) and (D).
Hence, the correct option is (C).
