$(18$ pts$)$ Oil flows from tank A through $150m$ of $150-mm$ new asphalt$-$dipped cast iron pipe to point $B$ in the figure below. What pressure will be needed at $A$ to cause $0\mathrm{.}013\frac{m^3}{s}$ of oil to flow? $($

Sp$.$Gr$.=0\mathrm{.}840$ and $v=2\mathrm{.}11{10}^{-6}\frac{m^2}{s}.)$ Use $=0\mathrm{.}00012m.$

$D=150mm(\frac{1(m)}{1000(mm)})=0\mathrm{.}15m,P_B=0$
