- Homework Statement
- Shown in the diagram below is a U-Tube with water on the left side and oil on the right. The system is in equilibrium. The horizontal line ##\mathbf{AB}## is drawn such that it passes through water through the left tube and through oil in the right tube. Are the pressures the same along this line in the right and left tubes?
- Relevant Equations
- Absolute pressure at a point of depth ##h## due to a liquid is ##P_A = P_G + P_{\text{atm}}##, where ##P_G = \rho_L gh## is the gauge pressure due to the liquid of density ##\rho_L## and ##P_{\text{atm}}## is the atmospheric pressure.
Yes, pressure is same along the line for both the tubes since the liquids are in equlibrium. (I ignore the slightly longer air column in the left compared to the right).
Is my answer correct?
