Characteristic Curve of a Centrifugal Pump

[Michael V]

Homework Statement

The pump characteristic curve of a centrifugal pump can be plotted from the following details:

(See attachment)

The pump delivers 90 L/s when pumping against a static head of 12 m. Plot the pump characteristic curve from the details given and calculate:

1. The quantity of water delivered in L/s.
2. The total head pumped against, if the static head and pipe length are increased by 30%.

Homework Equations

[itex]H_{Total}[/itex] = [itex]H_{static}[/itex] + [itex]H_{friction}[/itex]

[itex]\frac{H_{f1}}{H_{f2}}[/itex] = [itex](\frac{Q_{1}}{Q_{2}})^{2}[/itex]

The Attempt at a Solution

If anyone can help me where to start. I drew the curve and now I'm completely stuck and confused. Any help will be greatly appreciated.
