Question: A hydrofoil moves with speed V at a depth D = 3m below the surface of a lake; see Fig. 13.7. Estimate how fast V

A hydrofoil moves with speed V at a depth D = 3m below the surface of a lake; see Fig. 13.7. Estimate how fast V must be to make the water next to the hydrofoil boil. This boiling, which is called cavitation, results from the pressure P trying to go negative.
