Which of the following is not a term used to rank the distance between bars in a bar screen?

The term "wide" is not commonly used to rank the distance between bars in a bar screen. In the context of bar screens, which are used in water treatment processes to filter out debris and larger particles from water, the terms "fine," "medium," and "coarse" are used to describe the spacing between the bars.

"Fine" indicates closely spaced bars that can capture smaller particles, while "coarse" refers to wider spacing that is suitable for capturing larger debris. "Medium" serves as an intermediate classification for spacing. These terms help operators select the appropriate bar screen design based on the size of the materials being filtered. In contrast, "wide" is not technically a classification used in this context, making it the correct choice for the question.
