Velocity and Flow Rate Example $2$:

Fluid with $=892k\frac{g}{m^3}$ flows at $1\mathrm{.}388$ liters$/$second through a $2^{\text{'}\text{'}ID}$ pipe, then into a $3^{\text{'}\text{'}}$ ID pipe,

then splits into two $1^{\frac{1}{2}}{?}^{\text{'}\text{'}}II$ pipes. What is the velocity in each section?

$($Note: $1ft=12in$;$1ft=0\mathrm{.}3048m$;$1m^3=1,000L)$
