  • a)
    0.133 m
  • b)
    0.332 m
  • c)
    0.644 m
  • d)
    0.75 m
Correct answer is option 'B'. Can you explain this answer?

In a sudden contraction, the velocity head changes from 0.5 m to 1.25 ...
  • The head loss in a sudden contraction is calculated using the formula:
    Head Loss = (1 - Cc)2 * (V22 - V12)/2g
Given:
  • Initial velocity head, V12/2g = 0.5 m
  • Final velocity head, V22/2g = 1.25 m
  • Cc = 0.66
  • Substitute values:
    Head Loss = (1 - 0.66)2 * (1.25 - 0.5) = 0.332 m
  • The correct answer is B: 0.332 m.
