Wаter flоws frоm а reservоir through а cast iron pipe and a turbine, then exits to the atmosphere. Given: Pipe length: L=125 mL = 125 text{m} Diameter: D=5 cmD = 5 text{cm} Elevation difference: Δz= 31 m Flow rate: Q=0.004 m3/sQ = 0.004 text{m}^3/text{s} Fluid properties (water at 20∘C20^circ C: ρ=998 kg/m3,μ=0.001 kg/(m. s) Cast iron roughness: ε=0.26 mm,f≈0.0316varepsilon = 0.26 text{mm}, quad f approx 0.0316 What is the power extracted by the turbine (W)? Please extract the required minor losses K value from the figure and tables to solve the problem.
