A submarine can be treated as an ellipsoid with a diameter of $6$ $m$ and a length of ${30}$ $m$. Determine the power required for this submarine to cruise horizontally and steadily at $44$ $km/h$ in seawater whose density is $1025$ $kg/m^3$. Also, determine the power required to tow this submarine in air whose density is $1.25$ $kg/m$. Assume the flow is turbulent in both cases. Power required to cruise horizontally = $W$ Power required to to submarine = $W$
