Question

Two points (X and Y) in a fluid are at the same depth in a container. The pressure at X is greater than the pressure at Y. Which of the flowing must be true

Answer 1

ρ_ x > ρ_ y

Step-by-step explanation:

The pressure in a fluid depends on its depth with the equation

P = ρ g h

For two points at the same depth there may be several possibilities,

- the pressure is the same if the density of the fluid is equal in the two points

- The pressure is different if the fluid density is different at each point

In this case, as the point x has greater pressure than the point, the density of the fluid in Des is greater than the density of the fluid in Y

ρ_ x > ρ_ y
