Water flows at 0.15 m³/sec from a lake through a turbine as shown in the figure. Water properties, pipe characteristics are as follows:

Fluid Properties
Specific weight of water \(=9,800 \mathrm{~N} / \mathrm{m}^{3}\)
Atmospheric pressure \(=1.01 \times 10^{5} \mathrm{~N} / \mathrm{m}^{2}\)
Reynolds Number \(=2000\)
Darcy Friction factor, \(f=0.032\)

Pipe Characteristics
Length \(=20 \mathrm{~m}\)
Diameter \(=120 \mathrm{~mm}\)

Neglecting all minor losses, the extracted turbine head (m) is most nearly:
