(C) According to Bernoulli's equation for streamline flow of an incompressible,non-viscous fluid:$p + \frac{1}{2} ho v^{2} + ho g h = 	ext{constant}$In the given horizontal pipe,the height $h$ is constant for all sections.Therefore,the equation simplifies to:$p + \frac{1}{2} ho v^{2} = 	ext{constant}$According to the equation of continuity,$A_{1}v_{1} = A_{2}v_{2}$. Since the middle section of the pipe is narrower ($A$ is smaller),the velocity of the fluid $(v)$ must increase in that section to maintain a constant flow rate.As the velocity $v$ increases in the narrow section,the pressure $p$ must decrease to keep the sum constant.Therefore,the water level in the middle vertical pipe will be lower than the water levels in the wider sections on the left and right. The correct representation is shown in the solution image.

The figures below show water flowing through a horizontal pipe from left to right. Note that the pipe in the middle is narrower. Choose the most appropriate depiction of water levels in the vertical pipes.
