Which outcome occurs when a bypass valve experiences rapid cycling?

💡 Explanation

Pressure oscillations appear because **valve stiction** introduces hysteresis. Limited flow amplifies instability; therefore system resonance worsens, rather than improves, system dampening because hysteresis impacts high-frequency oscillation.
