A $15-$hp $($shaft power$)$ pump is used to raise water to a $30-$m higher elevation between two

large open reservoirs. The flow rate of water is $25\frac{L}{s}.$ If the mechanical losses of the piping is

$8m$ which one of the following is the mechanical efficiency of the pump. Take water density as

$998k\frac{g}{m^3}$
