Prblm $3-31$: Determine the discharge pressure in psi

that must be developed by a pump in order to pump

$4$ cfs of water $($at $73F)$ through a ${36}^{\text{'}\text{'}}-$diameter

horizontal riveted steel pipe line $30,000\text{'}$ long with

atmosphereic pressure at the discharge end of the

pipe. Compare results by following methods:

a$.$ Colebrook$-$Moody, with $lon=0\mathrm{.}01ft$

b$.$ Hazen$-$Williams, with $C=110$

c$.$ Manning, with $n=0\mathrm{.}015$

d$.$ Scobey, with $K_s=0\mathrm{.}45$
