A nozzle is fitted at the end of a pipe of length 300 m and diameter 100 m. For the maximum transmission of power through the nozzle, find the diameter of nozzle. Take f = 0.009.

Data :

L = 300 m (Length of pipe)

D = 100 mn = 0.1 m (dia. of pipe)

F = 0.009

Diameter of nozzle d = ?

For maximum transmission of power, the diameter of nozzle is

$d = (\frac{D^5}{8fL})^1/4 = (\frac{0.1^5}{8 \times 0.009 \times 300})^1/4$

d = 0.02608 m

d = 26.08 mm
