A nozzle is fitted to a pipe 120 mm in diameter and 250 m long, with coefficient of friction as 0.01. if the available head at the nozzle is 100 m find the diameter of the nozzle and the maximum power transmitted by a jet of water discharging freely out of a nozzle.

Given :

Diameter of pipe D = 120 mm = 0.12 m

Length of pipe L = 250 m

Co-efficient of friction F = 0.01

Head available at nozzle = 100 m

For maximum power transmission through nozzle, the diameter at the outlet of nozzle (d),

$d = (\frac{D^5}{8fL})^1/4 = …
