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 57 mm below the level of mercury in the left limb. If the difference of mercury
level in the two limbs is 134 mm, determine the gauge pressure of the oil in the pipe in
Pascal. The specific gravity of the oil & mercury is 0.7 and 13.6 respectively.
Solution:
