Question 1 of 205eccef9cbacbc34ba4d457f4

During the operation of a flash-type evaporator, the distillate flow meter indicates the output has significantly decreased from the previous day. Although all shell pressures appear normal, which of the following could be the probable cause for the decrease in output?

🔍 Key Concepts

• Operation of a flash-type evaporator and how feed water temperature affects flashing and distillate rate • Relationship between shell pressure, steam supply, and distillate production • Difference between problems that reduce actual production vs. problems that affect measurement or losses after production

💭 Think About

• Which choice directly changes how much water actually flashes into vapor inside the evaporator, assuming shell pressures are normal? • Which choice would more likely cause a change in readings without changing the internal flashing conditions? • Think about whether changing the temperature of the incoming feed or the temperature of the outgoing distillate has the bigger impact on how much vapor is produced in a flash evaporator.

✅ Before You Answer

• Verify which option would change the energy available for flashing the seawater at the same shell pressure. • Check which option would mainly cause a leak or loss after distillate is formed, rather than reducing how much is formed. • Confirm whether changing distillate discharge temperature significantly alters the flashing process compared with changing feed temperature into the evaporator.
