174- In the figure below, two cylindrical containers have equal base diameters. If we open the valve connecting the two containers, how many centimeters will the water level rise? (density of oil $= 800\,\dfrac{\text{kg}}{\text{m}^3}$ and density of water $= 1000\,\dfrac{\text{kg}}{\text{m}^3}$) [Figure: Two connected cylindrical containers, each with base diameter $50\,\text{cm}$; left container has water (height $50\,\text{cm}$), right container has oil (height $50\,\text{cm}$), connected at the bottom by a valve.]
