Which risk increases when designing a pump that transports near-critical fluids?

💡 Explanation

Pump cavitation risk increases because the *compressibility divergence mechanism* is amplified near the critical point, meaning tiny pressure drops induce rapid vaporisation. Therefore cavitation occurs earlier, rather than alternative electrical or mechanical failures, because the fluid properties are uniquely vulnerable .
