AThe pump supplies the motive force to the ejectors and removes the excess distillate.
BThe pump is used to drain the shell when the unit is secured, in addition to powering the ejectors.
CThe pump provides for venting of associated equipment while also powering the ejectors.
DThe pump supplies the motive fluid to the ejectors in addition to supplying the feedwater to the distiller.
AI Explanation
The correct answer is D. The pump supplies the motive fluid to the ejectors in addition to supplying the feedwater to the distiller. This is correct because the pump labeled "20" in the illustration is responsible for two primary functions - powering the ejectors that remove excess distillate, and supplying the feedwater to the distiller unit. The pump provides the motive force to drive the ejectors as well as delivering the necessary feedwater to the distillation system. The other options are incorrect because they do not fully capture the dual role of the pump in both powering the ejectors and supplying the feedwater, which are the two major functions provided by the item labeled "20" in the illustration.
