c) Determine the new differential reading along the inclined leg of the mercury manometer of Figure 1, if the pressure in pipe A is decreased 10 kPa, and the pressure in pipe B remains unchanged. The fluid in A has a specific gravity of 0.9 and the fluid in B is water.

A piezometer was connected to a pipe to measure the pressure of water. The rise of water level in piezometer was 150 mm. Calculate the pressure of water. 150 mm Q A U-tube manometer is connected to a pipe for measuring the pressure of oil (Specific gravity 0.92) flowing in the pipeline. Mercury (Specific gravity 13.6) is used as manometer liquid and the difference of mercury level in the two limbs is 200 mm. The centre of pipe is 80 mm below the level of mercury in the right limb. Determine the pressure in the pipeline and the head. | 80 mm 160 mm

5. A manometer tube which contains mercury shown in figure below is used to measure the pressure Pa in the air pipe. Determine the gage pressure PA. Specific gravity of Hg= 13.6 times the specific gravity of H,O. Air pipe 3 m Hg

The gauge pressure of a pneumatic cylinder reads 40 lb/in.? when the Ib/in.?, volume is 30 in.3. The cylinder is compressed until the gauge reads 60 Part 1: What is the absolute pressure before the cylinder gas is compressed? (number only, psi)
