The tank shown below has a single drain

pipe at the bottom, with a diameter equal

to $4$ centimeters. Water is fed to the tank

from the faucet with a volumetric

flowrate of $576c\frac{m^3}{sec}.$ The velocity of

water exiting the tank drain at the bottom

is equal to $35\mathrm{.}3c\frac{m}{sec}.$ If the tank is dry

at the start, how much water $($in

kilograms$)$ will be held in the tank after

$15$ minutes? Assume the density of water

to be $997\mathrm{.}1k\frac{g}{m^3}.$ Report your answer to

one decimal place.
