An engineer is installing an openend mercury manometer attached to a pipe that will eventually carry pressurized gas. While the pipe is open to the atmosphere, she adds enough mercury into the manometer so that the mercury level in both arms of the manometer is i=740.0 mmi=740.0 mm above the bottom of the manometer (see figure 1).

If the end of the open arm of the manometer is f=1100.0 mmf=1100.0 mm above the bottom of the manometer, what is the maximum pressure (gauge) of the pressurized gas that the pipe can carry before the mercury spills out of the open end of the manometer (see figure 2)?

maximum pressure:
