Problem 11.10
The rate of flow of water through a horizontal pipe is 0.25 m/s. The diameter of the
pipe which is 200 mm is suddenly enlarged to 400 mm. The pressure intensity in the smaller pipe is
11.772 N/cm². Determine:
(i) loss of head due to sudden enlargement, (ii) pressure intensity in the large pipe,
(iii) power lost due to enlargement.
