Oil flows through the system shown in the figure below with negligible losses. Determine the flow rate.

Hint:

Apply hydrostatics to determine $($p$1-$p$2)$

Apply Bernoulli's equation between points $1$ and $2$ to determine $v2.$ Note that $z1=0$ and $v1=0,z2=1\mathrm{.}5m.$

Find the volumetric flowrate in $\frac{m^3}{s}$ using $Q=A2**v2$
