@X@user.full_name@X@ @GMU: Closed-tube manometers work exactly as barometers except by connecting them to a container its pressure can be measured. Assume you have a closed-ended manometer filled with an oil having a density of 0.7958 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure if the height of the oil column is 1126.49 cm?
