Which statement best restates the cycle time concept in tank cleaning?

• A. 30 min
• B. Time to rotate through all angles
• C. The rate of flow
• D. Vessel volume

Answer: (B)

Cycle time in tank cleaning is about how long one complete cleaning sweep takes as the cleaning head moves through all the required spray angles to expose every surface to the cleaning action. It includes repositioning the head and the time it spends at each angle, so the entire cycle covers the full range of surfaces needing cleaning. This is why it’s about the duration of the full sweep through all angles, not a fixed clock time, not the cleaning solution’s flow rate, and not the vessel’s size. So the best restatement is the time to rotate through all angles—the full sweep needed to achieve complete cleaning.
