A centrifugal pump takes brine from the bottom of a supply tank and delivers it into the bottom of another tank $($Fig$.1).$ The brine level in the discharge tank is $45$ m above that in the supply tank. The line between the tanks is $185$ m of $4-$inch Schedule $40$ pipe. The flow rate is $400$ gal$/$min$.$ In the line are two gate valves, four standard tees, and four elbows. The specific gravity of brine is $1\mathrm{.}18,$ the viscosity of brine is $1\mathrm{.}2$ Cp$,$ the pipe roughness is $0\mathrm{.}0000457$ m$,$ and the energy cost is $$25$ per kW$-$year on a basis of $300$ days$/$yr$.$ The overall efficiency of pump and motor is $60$ percent.

Determine the energy cost for running this pump for one $24-$hr day?
