Pascal principal p = ρgh

The Attempt at a Solution

Pressure at C and D is the same .
Pressure at A and B is the same ? I believe it is

 

[Chestermiller]

Pressures at c and d are the same. Pressures at a and b are not the same. Do you know why?

 

[Mariog]

Because of different fluids ?

And how the fluids are in balance if A and B pressures are not the same ?

 

[Chestermiller]

Because of different fluids ?

yes

And how the fluids are in balance if A and B pressures are not the same ?

$$p_A+\rho_{left}g(x+h)=p_D$$
$$p_B+\rho_{right}g(x+h)=p_C$$
