Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
If the diameter doubles (x2), the cross-sectional area quadruples (x4).
Other things being equal, more cross-sectional area will cause less resistance.

It depends on what you mean by a 30 pipe. Is 30 the cross sectional area - in which case, what is the length of the pipe? Is 30 the length - in which case, what is the cross-sectional area?
Yes, We can design a cross sectional study which its data collected in a retrospective format, so this study is called cross sectional retrospective study.
Cross-sectional design involves studying different groups of individuals at a single point in time, whereas cross-sequential design combines both cross-sectional and longitudinal elements by studying different age groups over a period of time. Cross-sectional design allows for quick and easy comparisons between different age groups, while cross-sequential design allows researchers to track the same individuals as they age.
A cross sectional design is a developmental design where multiple samples of participants of different ages are tested at once. Cross sectional research design gathers data about different ages at the same time. Also participants only have to commit for a short time.
Cross sectional
A cross-sectional design does not control for cohort effects because it involves studying different age groups at the same point in time, making it difficult to separate age effects from cohort effects.

advantage of cross sectional study?
You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
the larger the cross sectional area, the smaller the resistance
Cross Sectional Area = Width x Average Depth
