1. How do the head, Hp, input power, P, and output power, Po, change as flow rate, Q, increases from its minimum to its maximum values? Consider that individual variables in each equation will have different rates of change. Explain why using specific references to equations, concepts, and results 2. How is efficiency, ep, calculated? 3. How does efficiency, ep, change with respect to flow rate, Q? Consider that individual variables in each equation will have different rates of change. Explain why using specific references to equations, concepts, and results. 4. How does efficiency, ep, change with respect to pump speed? Including a plot of Efficiency vs. Pump Speed (Y vs. X) may help you visualize the answer to this question. 5. Comment on any potential errors in the measured data. Consider the effects of human error, mechanical error, or influences from system instability.
