🔍 Key Concepts

• Identify what device 7 is by its symbol (type of pump) and where it sends water in the system. • Recall how wearing ring wear affects a centrifugal pump’s capacity and discharge pressure (more internal leakage, less effective flow). • Relate the feed‑water flow from device 7 to the evaporation rate inside unit 23 (more/less feed, more/less evaporation).

💭 Think About

• Follow the piping from device 7: what fluid is it moving, and directly or indirectly, how does that fluid enter unit 23? • If the pump’s wearing rings are badly worn, will the pump move more water, less water, or the same water at the same speed and suction conditions? • Ask yourself whether the standby pump (8) comes on automatically just because the rings in 7 are worn, or if some action would be needed to use it.

✅ Before You Answer

• Confirm from the symbol that device 7 is not a positive displacement pump and that it would normally use wearing rings. • Verify whether evaporation rate in 23 depends on the amount of seawater/feed water delivered or only on vacuum conditions. • Decide if worn wearing rings would reduce effective discharge flow or pressure from 7, and then infer how that would influence the amount of water available for evaporation in 23.

Question 1 of 20

If the wearing rings of device "7" shown in the illustration become worn, how will the evaporation rate in "23" be affected? Illustration MO-0111

The rate of evaporation is dependent on the level of vacuum maintained within the unit, and not the flow of water to the unit.

The rate of evaporation will decrease.

The rate of evaporation will not be affected as the standby pump, labeled "8" will be used instead.

Device "7" does not use wearing rings, as these are normally positive displacement pumps.
