Q$2)$ Consider a pump$-$pipeline system that delivers water from reservoir A to B with $E_A=45\mathrm{.}5m$ and $E_B=52\mathrm{.}9m$ The pipe has a length of $L=3050m,$ diameter of $D=0\mathrm{.}5m,$ and a DarcyWeisbach friction factor of $f=0\mathrm{.}02.$ Minor losses include an inlet $K_e=0\mathrm{.}5,$ exit $K_d=1,$ and swingtype check valve $K_v=2\mathrm{.}5.$ The pump characteristics are shown in the following table. Determine the flow rate in the pipeline if two identical pumps are used in a series combination. Also, determine the flow rate in the pipeline if two identical pumps are used in a parallel combination.
