Question

Please answer the red sentences is the hint

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 that the mercury level in both arms of the manometer is 790.0 mm above the bottom of the Pipe open to manometer. (See Fig. 1) If the end of the open arm of the manometer is 1015.0 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 the open end the manometer? (See Fig. 2) Fig 1. 790.0 m Number 79.38psig Incorrect. Calculate the difference in height between the mercury levels in the left arm and the right arm of the manometer under pressurized conditions. Convert that height difference in mmHg to psig, by using the conversion factor: 14.696 psi 760 mmHg 1015.0 mm Fig 2.
