Q. 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. Evaluate the pressure of fluid flowing in the pipe if the difference of mercury level in the two limbs is 22 cm.
