Consider a U-tube manometer used to measure the density pa of liquid A, as shown below. Mercury is used as the base liquid for the manometer with density Phg = 13600kg/m³. If hng = 5mm and ha = 22.4 mm, find Pa. V ha Pa Phg A hng

A manometer showed in Fig. 1 (right) connects pipe A and pipe B. It reaches a balance at the showing state. Determine a) When the pressure in pipe A is increased from the current state by 32 kPa while the pressure in pipe B remains constant, the interface between water and mercury in the left leg of the manometer will go up or down? b) Calculate the change in the elevation of this interface.

Two ends of an U-tube manometer which contains mercury, is connected between two pipes (A & B) that carries oil of specific gravities 1.5 & 1.4 respectively. The center of the pipe B (right limb) is 14 cm above the pipe A (left limb). The mercury level difference in the Left limb is 2 cm, and the height of fluid in the left limb is 5.8cm, find the pressure difference between these two pipes in Pascal. Draw the diagram. The difference of pressure between the pipes A & B in (Pascal) =

The gage pressure in a pipe is measured by a manometer containing mercury (? =13,600 kg/m³). The top of the mercury is open to the atmosphere and the atmosphericpressure is 100 kPa. If the mercury column height is 24 cm, calculate the gagepressure in the pipe.
