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 sp. gr. 0.9 is flowing. The centre 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 20 cm.

For the open tank, the piezometers attached on the side, containing two different immiscible liquids, as shown in the figure, find the elevation of the liquid surface in piezometer A.

A manometer is attached to a water tank as shown in the figure. Find the height of the free water surface above the bottom of the tank. water 0.2m 0.15m 0.15m Hg(13.6)

You are required to design a barometer that uses water instead of mercury to operate under standard sea-level conditions. Draw a conceptual diagram of your barometer design. Show on your diagram what the pressures will be at all liquid-gas interfaces, and where the barometer reading will be taken.Calculate the minimum height requirement of the barometer tube to measure standard sealevel atmospheric pressure.

Current Attempt in Progress A U-tube manometer is connected to a closed tank as shown in the figure below. The air pressure in the tank is 0.50 psi and the liquid in the tank is oil (y = 54.0 lb/ft³). The pressure at point A is 2.00 psi. Determine: (a) the depth of oil, z, and (b) the differential reading, h, on the manometer. (a) z = (b) h = ft ft Air Oil SG = 3.01 2.0ft + Open h
