The discharge of water through a horizontal pipe is 0-25 m'/s. Its diameter, which is 200 mm, suddenly enlarges to 400 mm. If the intensity of pressure of water in the smaller pipe is 120 kN/m², determine : (1) Loss of head due to sudden enlargement, (ii) Intensity of pressure in the large pipe, and (ii) Power lost due to enlargement.

5. The discharge of water through a horizontal
pipe is 0-25 m'/s. Its diameter, which is 200 mm,
suddenly enlarges to 400 mm. If the intensity
of pressure of water in the smaller pipe is 120
kN/m², determine :
(1) Loss of head due to sudden enlargement,
(ii) Intensity of pressure in the large pipe, and
(iii) Power lost due to enlargement.
[Ans. (i) 1-816 m; (ii) 132 kN/m²;
(ii) 4-45 kW]
