Which outcome occurs when positive displacement pump suction lift exceeds vapor pressure during glycol coolant circulation?

💡 Explanation

System component overheating occurs because cavitation introduces vapor bubbles into the pump. Cavitation bubbles collapse violently, generating localized high temperatures, therefore overheating sensitive components rather than improving efficiency because density decreases and reduces the heat transfer capacity.
