Type II problem, determine Q$.($see Table $8\mathrm{.}4$ for Pipe Flow problem types$).$ Gasoline flows through a section of $80$ feet of galvanized iron pipe with inner diameter $1\mathrm{.}5".$ The section inlet and outlet pressures are $12$ and $9$ psig respectively. The flow is steady and fully developed. Determine the volumetric flow rate in cfs $($cubic feet per second$).$ You could use guess and check; start by guessing either average $V$ or $Q$ and then determine the assqciated $p$ after finding the associated f$.$ Your "guess" is correct when equation $8\mathrm{.}33$ gives $3$ psi pressure drop. $($You don't need to get the exact answer; $3$ guesses total is sufficient$).$
