A certain torpedo, moving in fresh water at 10 8 C, has a minimum-pressure point given bythe formulapmin = p0 - 0.35 ρV2 (1)where p 0 = 115 kPa, ρ is the water density, and V is the torpedo velocity. Estimate thevelocity at which cavitation bubbles will form on the torpedo. The constant 0.35 isdimensionless.
