- A submarine can be treated as an ellipsoid with a diameter of 5 m and a length of 25 m. Determine the power required for this submarine to cruise horizontally and steadily at 40 km/h in seawater whose density is 1025 kg/m3. Also determine the power required to tow this submarine in air whose density is 1.30 kg/m3. Assume the flow is turbulent in both cases.A wooden block having a weight of 50 N isplaced at a distance of 1.5 m from the center ofa circular platform rotating at a speed of 2rad/sec.
