A differential manometer is connected at the two points A and B of two pipes as shown below. Pipe A contains a liquid of specific gravity of 1.5 while pipe B contains liquid of specific gravity of 0.9. The pressures at A and B are 1 1.8 kgf/cm2 respectively. Find the difference in mercury level (h) in the differential manometer.

Q1 A U-tube manometer is used to measure the pressure of oil of specific gravity 0.85 flowing in a pipe line. Its left end is connected to the pipe and the right-limb is open to the atmosphere. The centre of the pipe is 100 mm below the level of mercury (specific gravity- 13.6) in the right limb. If the difference of mercury level in the two limbs is 160 mm, determine the absolute pressure of the oil in the pipe. Liquid (5,-ERS) Pips

In the inclined manometer shown in the figure below, the reservoir is large. Its surface may be assumed to remain at a fixed elevation. A is connected to a gas pipeline and the deflection noted on the inclined glass tube is 100 mm. Assuming q = 30° and the manometric fluid as oil with specific gravity of 0.86, the pressure at A is A 100 mm Ꮎ B
