Question

Imagine two tanks. Tank A is filled to depth h with water. Tank B is filled to depth h with oil. Which tank has the largest pressure? Why? Where in the tank does the largest pressure occur?

Answer 1

Tank A, due to higher density of water. At the bottom of the tank.

Step-by-step explanation:

According to the theory of hydrostatics, pressure change is the product of density, gravity constant and depth. The higher the density, the higher the depth. As oil (
`\rho_(oil) = 920 (kg)/(m^(3))`) has a density lower than in water (
`\rho_(water) = 1000 (kg)/(m^(3))`), the largest pressure occur in tank A. The highest pressure occurs at the bottom of the tank A due to the fluid column.
