Applied Hydraulics in Engineering

Prblm $3-22$: A flow of $3\mathrm{.}5$ cfs of oil $(=0\mathrm{.}00021lb-$

$s\frac{ec}{sqft}$ and $(=55l\frac{b}{c}$uft is pumped through an

$18"-$diameter horizontal riveted steel pipe $(lon={0\mathrm{.}02}^{\text{'}}).$

Pumps used on that line can increase the pressure

by $100$ psi $.$

a$.$ What horsepower must be supplied to each

pump, assuming $75\%$ effecients?

b$.$ How far apart can the pumps be placed along

the pipeline?

Answers should be $122$ hp and $27\mathrm{.}8$ miles
