Irregular feeding or surging of the feedwater supply to a flash evaporator may be attributed to __________.

Question 1 of 27070

Irregular feeding or surging of the feedwater supply to a flash evaporator may be attributed to __________.

🔍 Key Concepts

• Operation of a flash evaporator and how feedwater enters the system • Typical causes of surging or irregular flow in centrifugal pump suction lines • The effect of restrictions vs pressure issues on flow stability

💭 Think About

• Which of these components, if malfunctioning, would most directly affect the consistency of flow into the evaporator, rather than just pressure or vacuum level elsewhere? • Think about what happens at the suction side of a pump: what kind of problem there would make the pump alternately get enough water, then starve, then get enough again? • Which options deal with upstream flow restriction versus those that mainly affect vacuum or auxiliary systems?

✅ Before You Answer

• Identify which choice involves the suction side of the saltwater feed pump. • Decide which problem would most likely create intermittent starvation and then recovery of flow, i.e., surging. • Verify which items primarily affect the air/vacuum system rather than directly throttling the feedwater supply.
