Homework Statement
Two containers are connected with a u-tube as shown above. An steady equilibrium state is reached where oil with a density of ##900\frac{kg}{m^3}## exactly fills the left leg connected to the container with pressure ##p_1## and the other other leg is filled with water. What can you say about the pressure in the two containers?
Correct answer: ##p_1>p_2##
Homework Equations
##p-p_0=Δp=\rho gh##
The Attempt at a Solution
##p_{H_2O}=1000\frac{kg}{m^3}\cdot gh##
##p_{oil}=900\frac{kg}{m^3}\cdot gh##
Since their height is the same, the only difference is the density.
However going by the two equations, water seems to have the bigger pressure but that isn't the correct answer. Apparently the oil has the bigger pressure?
