Question
Problem 2 The figure below shows a new cast-iron pipeline that connects two reservoirs. The upstream reservoir is at an elevation of 1000 ft (assume this is 1000.00 ft). The flowrate in the system from the upstream reservoir to the downstream reservoir is 5 cfs. Assume the water temperature is 50 °F. The pipe length from the first reservoir to the globe valve is 300 ft, the pipe length from the globe valve to the enlargement is 700 ft. (a) Using the Darcy Weisbach equation for pipe friction head loss, find the elevation of the downstream reservoir. Account for minor losses. Also tabulate the total head at each of the following locations along the pipeline: A just after the sharp-edged pipe entrance, B before the globe valve, C after the globe valve, D before the enlargement, E after the enlargement, F before the pipe exit. Calculate all values with a lot of precision because cumulative round-off errors can add up, but report all head values to the nearest 0.01 ft. Submit a clearly annotated Moody diagram. (b) Repeat part (a) but use the Hazen Williams equation to calculate pipe friction head loss instead. Report the head values at points A through F in another column of the table you made for part (a). (c) Using your calculations from part (b) (and any other necessary calculations), draw the energy grade line (EGL) and hydraulic grade line (HGL) to scale. Use an entire sheet of GRAPH PAPER for this graph so you can draw it large enough. The horizontal scale should be different from the vertical scale. Elevation 1000 ft Globe valve 12-in. dia, 1000 ft 18-in. dia, 4500 ft Cast-iron pipe Elevation ?
