D$.)200\frac{L}{sec}$

$19.)$ A pump draws water form a reservoir $A$ at elevation shown and lifts it to reservoir $B$ at the glven elevation. The loss of head from $A$ to $1$ is three time the velocity head in the $200mm$ diameter pipe and the loss of head from $2$ to $B$ is $14$ times the velocity head in the $150mm$ diameter pipe. Determine the horsepower of the pump.

A$.)66\mathrm{.}675HP$

B$.)60\mathrm{.}333HP$

C$.)50\mathrm{.}313HP$

D$.)55\mathrm{.}098HP$
