Question

Problem 3 A pipeline delivers water from Reservoir 1 to Reservoir 2 as shown in the following figure. The water levels at Reservoirs 1 and 2 are 50 ft and 20 ft, respectively. A globe valve is installed in the pipeline with a minor head loss coefficient k 10. The pipe from Reservoir 1 to the globe valve is 1000 ft long and 6 inches in diameter. The pipe from the globe valve to Reservoir 2 is also 1000 ft long and 6 inches in diameter. The minor head loss 0.5 and 1.0, respectively. The Darcy-Weisbach friction factor for the pipes is 0.025. coefficients for the entrance and the exit are (1) Determine the discharge through the pipeline. Iculate and draw the energy grade line and hydraulic grade line on the figure below and alues at the following locations: (A) Reservoir 1, (B) immediately after entering the pipeline, (C) immediately upstream of the globe valve, (D) immediately downstream of the globe valve, (E) immediately before exiting the pipeline, and (F) Reservoir 2. (Note: Energy pipeline; Hydraulic grade line elevation + total energy along the presents the variation of piezometric head along the pipeline; Total energy pressure head+ velocity head; Piezometric head elevation+ pressure head) Reservoir 1 50ft Reservoir 2 20 ft EIF L-1000ft Globe6 in L- 1000 ft 0.025 vave d6 f= 0.025 valve f= 0.025
