Question: A torpedo 8 m below the surface in 20C seawater cavitates at a speed of 21 m/s when atmospheric pressure is 101 kPa. If Reynolds-number

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. If Reynolds-number and Froude-number effects are negligible, at what speed will it cavitate when running at a depth of 20 m? At what depth should it be to avoid cavitation at 30 m/s?
