Question

The right limb of a simple U tube manometer containing mercury is open to the atmosphere while the left limb is connected to a pipe in which a fluid of specific gravity 0.9 is flowing . The center of the pipe is 12 cm below the level of mercury in the right limb Find the pressure of fluid in the pipe if the difference of mercury level in the two limbs is 20cm .

Answer 1

Answer:

The right limb of a simple U-tube manometer containing mercury is open to the atmosphere while the lift limb is connected to a pipe in which a fluid of specific gravity 0.85 is flowing. The centre of the pipe is 14 cm below the level of mercury in the right limb. ... The difference in mercury level is 40 cm.
