CHAPTER 2: FLUID APPLICATION

6. A U tube manometer is used to measure the pressure of oil (s= 0.8) flowing in a pipeline as in Figure b.
Its right limb is open to the atmosphere and the left limb is connected to the pipe. The center of the pipe is
9 cm below the level of mercury in the right limb. If the difference of mercury level in the two limbs is 15

cm, determine the gauge pressure of the oil in the pipe in KPa.

Answer:
(19.541 KPa)

7. Figure j shown U tube manometer. If the differential of pressure between X and Y is 50KN/m2 , h=2m
and a=0.85m determine b.

Answer:
(0.4719m)

8. In the figure below, fluid Q is water and fluid P is oil (specific gravity = 0.9). If h = 69 cm and z = 23 cm,
what is the difference in pressure in kN/m2 between A and B?
