A simple U tube manometer is used to measure the pressure of oil flowing in a pipeline. Its left limb is open to the atmosphere and the right limb is connected to the pipe. The center of the pipe is 70 mm below the level of mercury in the left limb. If the difference of mercury level in the two limbs is 144 mm, determine the gauge pressure of the oil in the pipe in Pascal. The specific gravity of the oil & mercury is 0.84 and 13.6 respectively.

Solve it clearly please
A simple U tube manometer is used to measure the
pressure of oil flowing in a pipeline. Its left limb is
open to the atmosphere and the right limb is
connected to the pipe. The center of the pipe is 70
mm below the level of mercury in the left limb. If
the difference of mercury level in the two limbs is
144 mm, determine the gauge pressure of the oil in
the pipe in Pascal. The specific gravity of the oil &
mercury is 0.84 and 13.6 respectively.
Solution:
(i) Density of oil in kg/m3
(ii) Density of mercury in kg/m3
(iii) Height of the Oil in the right limb (in meters of
oil) h,
(iv) The gauge pressure of the oil in the pipe in (in
Pascal)
