Which outcome occurs when a pump exceeds its maximum specific speed, resulting in excessive turbulence?

💡 Explanation

Increased radial thrust occurs because the flow becomes unstable, inducing asymmetric pressure distribution on the impeller via turbulent kinetic energy excitation arising from off-design operation; therefore radial forces are created rather than axial because of uneven pressure exertion.
