- 3. Water is moving between two reservoirs at a flow rate of 0.08 m³/s via the pipes shown in the diagram (D₁ = 10 cm, D₂ = 20 cm). Assume both pipes have a roughness ks = 0.08 mm. If the difference in water surface elevation between the two reservoirs is 70 m and L₁ = 50 m, what is the length of the larger pipe (L2)? Further, what is the entrance length of pipe 1? For what fraction of the length of pipe 1 is flow fully developed? Include form losses due to pipe components (entrance, expansion, and exit) in your calculations. For more info on component losses, use Table 10.5 and 0 = 180°. Water T = 20°C D₁ D₂ 1₂2.arrow_forwardWater flows over the spillway shown in the figure below.
