Question:

The geometry of a centrifugal water pump is $r_{1}=10 \mathrm{~cm}$, $r_{2}=20 \mathrm{~cm}, b_{1}=b_{2}=4 \mathrm{~cm}, \beta_{1}=30^{\circ}, \beta_{2}=15^{\circ}$, and it runs at speed $1600 \mathrm{rpm}$. Estimate the discharge required for axial entry, the power generated in the water in watts, and the head produced.
