Figure shows an ideal fluid flowing through a uniform cross-sectional tube. In the vertical tube with liquid velocities ${\mathrm{v}}_{\mathrm{A}} \mathrm{and} {\mathrm{v}}_{\mathrm{B}}$ and pressure ${\mathrm{P}}_{\mathrm{A}} \mathrm{and} {\mathrm{P}}_{\mathrm{B}}$. Knowing that tube offers no resistance to fluid flow then which of the following is true.
