The length AB of a pipe ABC in which the liquid is flowing has diameter (d1) and is suddenly contracted to diameter (d2) at B which is constant for the length BC. The loss of head due to sudden contraction, assuming coefficient of contraction as 0.62, is
- Av²/2g
- Bv²/2g
- C0.5 v²/2g
- D0.375 v²/2g
Correct answer: D
