Question 201Steam Plants - Assistant Engineer
70% to passUnder normal conditions, the rate of heat transfer in a feed water heater is most greatly affected by the _______________.
Aspeed of the main feed pump
Bdensity of the feed water
CpH of the feed water
Dtemperature differential between the steam and feed water
AI Explanation
The correct answer is D) temperature differential between the steam and feed water. The rate of heat transfer in a feed water heater is most greatly affected by the temperature differential between the steam and the feed water. This is because heat transfer is driven by the temperature difference, with a larger temperature difference leading to a higher rate of heat transfer. The other factors, such as the speed of the main feed pump, density of the feed water, and pH of the feed water, have a less significant impact on the overall rate of heat transfer in the feed water heater.
