Figure 3 of piping system that is to be developed at Kg. Baru, Melaka. In the piping system a pump located at elevation 5 m is to pump water from tank with elevation of 3 m to a lower tank with elevation of 1 m. The plan designed flow is 0.15XX m³/s. Attached in the appendix is pump curves that is available to be selected for the design of piping system. There are three pumps curves; Pump A, Pump B and Pump C. NPSH required for Pump A, Pump B and Pump C respectively is 9 m, 7 m, and 5 m. Submit the answers together with the attached pump curves. Atmospheric pressure head is 1 m head and vapor pressure at 21° Celsius is 0.253 m head. (a) Develop a system curve equation based on the piping system with a single pump as shown in Figure 3. [8 Marks] (b) Plot a system curve based on the system curve equation on the attached pump curves sheet, starting from Q is 0.1 m³/s to Q is 0.2 m³/s with an increment of 0.05 m³/s. Determine the operating point of Pump A, Pump B and Pump C based on the system curve and determine the best pump for the piping system. Explain why you selected the pump based on the operating point of the pump. [6 Marks] (c) Plot Pump C in parallel on the attached pump curves and determine the operating point of the pump in parallel based on the piping system. Refer to the three plotting points on Pump C to plot Pump C parallel curve. [6 Marks] (d) Determine NPSH for the pump and explained whether it is safe to use the pump or not.
