Question

The loss due to sudden contraction is proportional to

• A. Velocity
• B. Velocity head
• C. Turbulence
• D. Pressure

Hint:

Head losses in fluid flow are typically functions of the velocity head.

Answer 1

The Correct Option is B

Loss due to sudden contraction or expansion in a pipe is proportional to velocity head:
\[ h_L = K \cdot \frac{v^2}{2g} \]
Where \( K \) is the loss coefficient and \( \frac{v^2}{2g} \) is the velocity head.
