An open-tube mercury manometer is used to measure the pressure in an oxygen tank. When the atmospheric pressure is 1040 , what is the absolute pressure (in ) in the tank if the height of the mercury in the open tube is 19.0 higher than the mercury in the tube connected to the tank? What is the absolute pressure (in ) in the tank if the height of the mercury in the open tube is 4.9 lower than the mercury in the tube connected to the tank?
