n > Plot a graph of Head H, against Flow Rate Q. On the secondary axis plot a graph of Mechanical Power P. and of Efficiency against Flow Rate Q. > Compare your results with figure 1 DISCUSSION AND CONCLUSIONS > Examine and describe the shapes of the graphs obtained, relating this to the changing performance of the pump as the flow rate changes. Locate the point of maximum efficiency and determine the maximum efficiency and the flow rate at which it occurs. > Compare the shapes of the curves obtained to the example presented in Figure 1. Discuss any similarities and differences in pump performance between the example presented and the pump tested./n
