The pressure in a natural gas pipeline is measured by a manometer with one arm open to the atmosphere (p_{atm} = 98 kPa). S_{Hg} = 13.6, S_{oil} = 0.69. Determine the absolute pressure in the pipeline (answer in kPa). [Columns met when walking from the open end to the pipeline: down 15 cm of mercury, down 65 cm of water, then up 35 cm of oil; the gas column is negligible.]
