What is LEAST likely to be used to strip a cargo tank?
Direct Answer
Option A: Centrifugal pump
A centrifugal pump is LEAST likely to be used for stripping cargo tanks effectively. These pumps lose suction and efficiency rapidly as liquid levels drop and air is entrained. Eductors, rotary, and reciprocating pumps are better suited for stripping due to their positive displacement or vacuum-creating capabilities.
