Which outcome occurs after a positive displacement pump experiences a sudden blockage in the discharge line during operation?

💡 Explanation

When the discharge line is blocked the fluid has nowhere to go: The fixed displacement attempts to force fluid against an immovable 'wall', and internal pressure buildup exceeds design stress limits because the pump continues to operate against a closed system. Therefore internal pressure exceeds design limits rather than cavitation, efficiency increase, or flow rate stabilization, which require open flow paths.
