Which of the following statements concerning the systems shown in the illustration is correct? Illustration MO-0111

Correct Answer: Option B — The feed water gains heat in section "23", while the vapor gives up heat in section "24".

In this system, the feed water is preheated as it passes through the condenser section (23) by absorbing latent heat from the condensing vapor. Subsequently, the vapor gives up its heat in the distiller section (24) as it condenses into distillate, completing the heat exchange cycle.
