Water of the same mass is poured into two barrels with different bottom areas. Is the water pressure on the bottom of these barrels the same?
No, not the same. If the mass of water is the same in both barrels, then the volume of water will also be the same. V = Sh, therefore, for that barrel, the bottom area of which is larger, the height of the poured water will be less, therefore, and the pressure exerted on the bottom will be less.
