Question No. 38
• 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 specific gravity 0.85 is flowing.
The centre of the pipe is 14 cm below
the level of mercury in the right
limb.Evaluate the pressure of fluid
flowing in the pipe if the difference of
mercury level in the two limbs is 22
cm.​

Answer 1

Answer:

The right limb of a simple U-tube manometer containing mercury is open to the atmosphere while the lift limb is connected to a pipe in which a fluid of specific gravity 0.85 is flowing. ... The difference in mercury level is 40 cm. On the left limb the fluid is upto the height of 20 cm.

Step-by-step explanation:

Explanation: Pressure at centre of pipe + Pressure at depth 8 cm in left limb = Pressure at depth 22 cm in right limb

P = 13600×9.81×0.22 – 850×9.81×.08

= 2.86 N/cm2.
