Which phenomenon causes increased drag on submarines when exceeding design speeds?

💡 Explanation

Drag increases because exceeding design speed amplifies instabilities resulting in boundary layer transition which increases momentum transfer via turbulent diffusion rather than viscous effects. Therefore turbulent drag increases sharply, rather than pressure or viscosity effects.
