Which of the following statements concerning...

🔍 Key Concepts

• Trace the flow paths of jacket water, feed water, and vapor through the system using the arrows and labels. • Identify what type of equipment sections 23 and 24 represent (evaporator vs. condenser/distiller). • Recall that heat always flows from the hotter medium to the cooler medium, and think about where phase change (evaporation/condensation) occurs.

💭 Think About

• Look at section 23: does the fluid inside it appear to be boiling/evaporating or condensing? Which medium is providing the heat there? • Look at section 24: is it receiving vapor or liquid? Is the fluid giving up heat or taking on heat in this section? • Follow the feed water line from its source: through which numbered components does it pass before it reaches the evaporating/boiling area? Where would it logically pick up heat along that route?

✅ Before You Answer

• Be sure which line is jacket water and which is feed water by following them back to their pumps and supply sources. • Confirm whether 23 is the evaporator (brine/sea water side) and 24 is the condenser (distillate side), or vice versa, based on inlets/outlets and phase changes. • Verify in the diagram where the vapor changes back to liquid; that section must be where vapor gives up its heat.

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

The jacket water primarily loses its heat at the cooler and is further heated in the evaporator section.

The feed water gains heat in section "23", while the vapor gives up heat in section "24".

The jacket water absorbs heat in the evaporator section, while giving up its heat in the distiller section.

The feed water acquires heat passing through devices "2"and "23".
