Pipeline AB connects two reservoirs. The difference in elevation between the two reservoirs is $33$ ft $.$ The pipeline consists of an

upstream section, $D_1=30$ in and $L_1=5000ft$ and a downstream section, $D_2=21$ in and $L_2=3500ft.$ The pipes are concrete

$(f=0\mathrm{.}016)$ and are connected end to end with a sudden reduction area. Compute the discharge capacity.

The total discharge from $A$ to $B$ in figure is $14$ cfs$.$ Determine the discharge in each pipe if the pipes used are cast Iron $($f$=0\mathrm{.}018)$
