An engineer is installing an open-end 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 h = 770.0 mm above the bottom of the manometer (see figure 1). If the end of the open arm of the manometer is he=1110.0 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)?

An engineer is installing an open-end 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 h; = 770.0 mm above the bottom of
the manometer (see figure 1).
If the end of the open arm of the manometer is
he=1110.0 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)?
