Question

Quizplus · Accepted Answer

The pressure at the bottom of a fluid is determined by the weight of the fluid above it. Since saltwater is denser than fresh water, there is more weight of water above any given point in the saltwater tube compared to the fresh water tube. Therefore, the pressure at the bottom of the saltwater tube is greater. The cross-sectional area of the tubes does not affect the pressure at the bottom.
