While the illustrated system is operated using the steam supply through "F" the strainer in line "4" becomes fouled, this will result in __________. Illustration GS-0053

Correct Answer: Option A — a reduction in distillate production

Restricting the steam supply via a fouled strainer reduces the heat input to the feed water. Since flash evaporation relies on the temperature differential between the feed and the flash chamber, a decrease in heat input directly lowers the rate of vapor production, reducing total distillate output.
