Question 4.12 A venturi meter with throat diameter of 100 mm is fitted in a vertical pipeline of 200 mm diameter. Oil with specific gravity of 0.88 is flowing upward at a rate of 0.06 m/s. A manometer is fitted at the throat and at the inlet pipe with Az = 320 mm. Working from Bernoulli's equation determine the difference in level in two limbs of a mercury manometer if it is connected to the tapping points and the connecting pipes are filled with the same oil.

![Question 4.12
A venturi meter with throat diameter of 100 mm is fitted in a vertical pipeline
of 200 mm diameter. Oil with specific gravity of 0.88 is flowing upward at a
rate of 0.06 m/s. A manometer is fitted at the throat and at the inlet pipe with
Az = 320 mm. Working from Bernoulli's equation determine the difference in
level in two limbs of a mercury manometer if it is connected to the tapping
points and the connecting pipes are filled with the same oil.
Question 4.14
A pitot-static tube is used to measure the air flowrate in a duct. A manometer
contains water is connected to the device to measure a pressure difference
between static and dynamic pressure.
If the flowrate in the pipe is 3.5 m/s and the diameter of the duct is 30
cm, determine the water column height in the manometer.
Sketch an appropriate diagram for the above system and label clearly
(a)
(b)
point 1, point 2 and the height of water column.
