A U-tube containing mercury (sg = 13.6) has its right-hand limb open to the atmosphere and the left-hand limb connected to a pipe conveying water under pressure, the difference in the level of mercury in the two limbs being 200 mm. If the mercury level in the left-hand limb is 400 mm below the pipe's center line, find the pipeline's absolute pressure (kPa). Also, find the new difference in levels of mercury in the U-tube if the pressure in the pipe falls by 2 kPa.

Question
A U-tube containing mercury (sg = 13.6) has its
right-hand limb open to the atmosphere and the left-hand
limb connected to a pipe conveying water under pressure,
the difference in the level of mercury in the two limbs being
200 mm. If the mercury level in the left-hand limb is 400 mm
below the pipe's center line, find the pipeline's absolute
pressure (kPa). Also, find the new difference in levels of
mercury in the U-tube if the pressure in the pipe falls by 2
kPa.
