Problem:

You have installed the following pump network $($Figure $1)$ into you water distribution system, but your intern accidentally threw away the cumulative pump curves $($He$/$She is so fired!!!$).$ Reconstruct the final curve in Excel, given that all pumps are the same and have the "base" performance curve as provided in Figure $2.$

Solve problem

Print out on a single graph

a$.$ Pump l$\text{'}$s curve

b$.$ Pump $2$&$3\text{'}$s curve

c$.$ System Curve $(1+2$&$3)$

Write out all relevant equations and how they were incorporated in your workbook

Bonus $(2$pts$)$:

Add a fourth pump to the system, just before the outlet, and construct the new pump curve.
