Consider a U-tube whose arms are open to the atmosphere. Now water is poured into the U-tube from one arm, and light oil is poured (p=790 kg/m) from the other. One arm contains 80.0-cm-high water, while the other arm contains both fluids with an oil-to- water height ratio of 4. Determine the height of each fluid in that arm. (Round the final answers to four decimal places.) P Water Oil The height of the water column is The height of the oil column is m. 3 m.
