Question

At what speed will the torpedo cavitate when running at a depth of 12 m? and

At what depth should it be to avoid cavitation at 25.5 m/s? 

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 speed will the torpedo cavitate when running at a depth of 12 m? The speed at which the torpedo will cavitate is |m/s.
