Required information A torpedo 8 m below the surface in 20°C seawater cavitates at a speed of 21 m/s when atmospheric pressure is 101 kPa. Consider Reynolds-number and Froude-number effects are negligible. For seawater at 20°C, take p = 1025 kg/m3 and py= 2337 Pa. At what depth should it be to avoid cavitation at 33 m/s? The depth at which the torpedo should be to avoid cavitation is m.
