A pipe of $0.7 \mathrm{~m}$ diameter has a length of $6 \mathrm{~km}$ and connects two reservoirs $\mathrm{A}$ and $\mathrm{B}$. The water level in reservoir $\mathrm{A}$ is at an elevation $30 \mathrm{~m}$ above the water level in reservoir $\mathrm{B}$. Halfway along the pipe line, there is a branch through which water can be supplied to a third reservoir $\mathrm{C}$. The friction factor of the pipe is $0.024 .$ The quantity of water discharged into reservoir $\mathrm{C}$ is $0.15 \mathrm{~m}^{3} / \mathrm{s}$. Considering the acceleration due to gravity as $9.81 \mathrm{~m} / \mathrm{s}^{2}$ and neglecting minor losses, the discharge (in $\mathrm{m}^{3} / \mathrm{s}$ ) into the reservoir $\mathrm{B}$ is
