A large tank feeds a straight pipe that delivers water to a turbine, and then exits to atmosphere, as shown in Figure P8.50. The friction factor f = 0.01, the length L = 100 m, the diameter of the pipe D = 0.1 m, the loss coefficients K1 = K2 = 1, the water density ρ = 1000 kg/m3 , the water viscosity µ = 15 × 10−3 N.s/m2 , the bulk velocity in the pipe V = 2 m/s, and the turbine develops 500 W. (a) Do you expect the flow in the pipe to be turbulent or laminar? (b) Find the height H.
