Question

Quizplus · Accepted Answer

The pressure at the bottom of the tube is determined by the density of the fluid and the height of the column, regardless of the cross-sectional area of the tube. Salt water is denser than fresh water, therefore the pressure is greater at the bottom of the tube with salt water.
