c) QUESTION 3 Water at 25C flows in a pipe from a lower reservoir to a higher reservoir with water free surface difference of 12 m. The pipe system consisted a globe valve, two standard elbows and driven by 1 kW pump as shown in Figure Q3. P 1-25m d-2-5cm b) a) Figure Q3 Supported by appropriate calculation, determine the roughness (in mm) of the pipe, if the pipe total length and diameter are 25 m and 2.5 cm, respectively and the globe valve is fully open causing the water to flow at a flowrate of 0.0022 m/s) Refer Moody Diagram as in Appendix. (6 marks) Sketch the Energy Grade Line (HGL) and Hydraulic Grade Line (HGL) with appropriate labelling. (2 marks) Due to the limited space that is available to place the pump, there is a suggestion to relocate the pump closer to the higher reservoir. As an engineer, would you recommend that the pump be placed near a higher reservoir? Justify your answer. (2 marks)
