PROBLEM NO$.$ B$-14$

$560ga\frac{l}{m}in$ of $70F$ water is pumped from the bottom of a tank through $700ft$ of $4$ in schedule$-40$ steel pipe. The line is elevated $50ft$ in the direction of flow. The combined friction and minor losses is given as $130ft.$ The inlet pressure is $50$ psig, and a working pressure of $20$ psig is needed at the outlet end of the pipe. The number of feet of head delivered to the system by the pump is most nearly:

$($A$)50$

$($B$)110$

$($C$)140$

$($D$)180$
