First you need to plot H and Power versus Q. I have done so the Excel sheet.
You then calculate the system head by using the formula
For pumping between lakes:
= 60 +0.006*(12+108)*Q2/(3d5) (see excel sheet)
Plot this hsys versus Q.
The solution provides detailed and step-by-step explanation and answer (including graphs) for the problem.
