The hydrofoil shown in Figure 5.70 was tested, and the minimum pressure on the surface of the hydrofoil was found to be 70 kPa when the hydrofoil was submerged 1.83 m and towed at a speed of 8 m/s. At the same depth, at what speed will cavitation first occur? Assume irrotational flow for both cases and a water temperature of 10◦C.
