Applied Hydraulics #$3\mathrm{.}5\mathrm{.}11$

A $2,500-$ft long pipeline is required to carry $21\mathrm{.}5$ cfs $($ft$3/$sec$)$ of water to an industrial client. The limiting pressure drop mandated by the client is $40$ psi $($lb$/$in$\mathrm{.}2).$ Determine the pipe size required if the material available is polyvinyl chloride $($PVC$)$ and the pipeline is level $($horizontal$).$ Assume that minor losses are negligible and the water temperature is $68$ farenheit.
