Question 5 Two pipes are connected in series and are used to transfer water from Reservoir A to Reservoir B. Both pipes have an equivalent sand roughness, ks, of 0.06 mm. A steady flow rate of 0.12 m³/s is maintained in the pipes. The pipe diameters and lengths for pipe 1 and pipe 2 are D₁ = 200 mm, L₁ = 100 m; and D₂ = 300 mm, L₂ = 250 m, respectively. Assume that the kinematic viscosity of water is 1x106m²/s . The entrance loss coefficient K; is 0.5, the exit loss coefficient K, is 1.0. The (V₁− V ₂)² 2g equation for minor loss at the expansion joint is where V, and V₂ are the flow velocities in pipe 1 and pipe 2, respectively, and g is acceleration due to gravity. Determine the difference in water surface elevation (H) between the two reservoirs.
