Required information

A centrifugal pump has $d_1=7in,d_2=13in,b_1=4in,b_2=3in,{}_1=25,$ and ${}_2=40$ and rotates at $1205\frac{r}{m}in.$ The fluid is gasoline at $20C$ and the flow enters the blades radially. For gasoline, take $$~~$1\mathrm{.}32$ slug$/$ft ${?}^3.$

Estimate the theoretical flow rate.

$f\frac{t^3}{s}$

Estimate the horsepower and head in ft $.$
