Which outcome occurs when a pump exceeds a radial turbine's design flow rate?

💡 Explanation

The increased exit velocity causes substantial separation and backflow behind the blades, generating turbulence. This mechanism, Von Karman vortex shedding then imparts fluctuating loads. These loads then decrease blade fatigue life because the stress exceeds endurance limits rather than improve performance.
