A pump needs be sized to drive water flow from a storage tank to an absorption

unit. There is a closed cylindrical water storage tank with a diameter of $100$ ft$,$ a

water height of at least $10$ ft$,$ and an internal pressure of $1$ psig. The water tank

is on the ground and will be used to provide a constant $2\mathrm{.}228$ ft$3/$s flow through

an equivalent length of $100$ ft of $6$ NPS$,$ schedule $40$ steel pipe $($so SG$=$

$11\mathrm{.}10$ ft $/$s $)$ to the open top of an absorption tower which is $20$ ft above ground

level. The friction through the entire length of pipe is $199\mathrm{.}5$ ft$2/$s$2.$

$-$ What is the minimum pump power $($e$.$g$.,$ in hp$)$ necessary to ensure the

desired flow can be delivered?
