For the centrifugal pump lab report.

We plotted graph with efficiency, total head and shaft power on vertical axes against flow rate on the horizontal axis.

I wonder why the Manufacturer data curve and experimental result curve are different.

Solution

1. Calculate the degree of undermines “n”;

2. Choose a rational analysis scheme for method of force

3. Calculate diagrams from unit loads and actual forces;
