Diagram for question 53
AI Explanation
The correct answer is D: The pump supplies the motive fluid to the ejectors in addition to supplying the feed water to the distiller. This is correct because the pump labeled "20" in the illustration is responsible for two key functions - providing the motive force to power the ejectors, and supplying the feed water to the distillation unit. The pump is a critical component that enables the overall desalination system to operate effectively. The other answer choices are incorrect because they do not fully capture the dual roles of the pump. Option A describes only one function, option B mentions draining the shell but not powering the ejectors, and option C refers to venting rather than supplying feed water.
