Same pressure points , 2 fluids u shaped tube

Click For Summary
SUMMARY

The discussion centers on the pressure dynamics in a U-shaped tube containing two different fluids, analyzed using Pascal's principle, expressed as p = ρgh. It is established that the pressures at points C and D are equal, while the pressures at points A and B differ due to the presence of different fluids. The equilibrium of the fluids is maintained despite the pressure difference at A and B, as demonstrated by the equations p_A + ρ_left * g(x+h) = p_D and p_B + ρ_right * g(x+h) = p_C.

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

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

yes
And how the fluids are in balance if A and B pressures are not the same ?
$$p_A+\rho_{left}g(x+h)=p_D$$
$$p_B+\rho_{right}g(x+h)=p_C$$
